2013 to bring new hotel, new casino to local gamblers | TribLIVE

A hotel at The Meadows, a casino in Fayette County and new games are on tap for Western Pennsylvania gamblers in 2013.

Regulators will award the license for the state?s 13th casino, as gambling industry leaders hope Americans have enough confidence in the economy to keep the slots spinning and the cards turning.

?We?re a discretionary income business,? Rivers General Manager Craig Clark says of casinos in general. ?We?re one of the first to be cut? when people have to reduce their spending.

In the first 11 months of the year, Pennsylvania casinos generated $2.9 billion in gambling revenue, an increase of 4.7 percent from the total through November 2011. With an eye toward increasing that figure again in 2013, casino executives plan new offerings to attract new players and keep familiar faces returning.

Lady Luck Casino Nemacolin will open in the summer at the Fayette County resort, says Isle of Capri spokeswoman Jill Alexander. Isle of Capri, which operates 15 casinos in six other states, will manage Lady Luck.

It will have 600 slot machines and 28 table games but no poker room, Alexander says. The casino will have 450 employees.

Lady Luck Nemacolin will be a resort casino, meaning it will be open only to hotel guests and to people making a $10 purchase, such as food, a souvenir or a gift card. Managers of existing Western Pennsylvania casinos say they don?t worry about competition specifically from Lady Luck.

?Nemacolin will have some minor effect, but I don?t think it will be dramatic,? says Sean Sullivan, vice president and general manager at The Meadows Racetrack and Casino in North Strabane. ?It?ll be attractive to certain types of players.?

Clark sees Nemacolin as more of a destination location, while most Rivers customers come from Allegheny County.

The Meadows

Officials are ?working tirelessly? on a hotel that will be connected to the casino, Sullivan says. He expects groundbreaking in the spring.

The hotel will have about 200 rooms. Although about 1,000 rooms are available in nearby hotels, Clark says an on-site facility is a ?critical component? for casino guests. ?Meadows Hotel? will be built below the south parking garage, in an area now used for bus parking.

Work also is to start in the spring for a retail development tentatively called ?The Street.? It will front on Racetrack Road and include shops, restaurants and a bank. Tenants might be announced next month.

Rivers

The casino recently remodeled its poker room and installed a new high-limit room.

Clark says Rivers? focus in 2013 will be on slot machines and promotions. The casino plans to add new slots and get new titles out faster. He says promotions will be bigger and more exclusive. The $300,000 ?mortgage mania? promotion in January offers to cover the winner?s mortgage payments for a year, up to $18,000, with secondary prizes of making car and credit card payments.

The casino will continue its emphasis on community involvement, he says. It will again be a partner with the Auto Show and plan a NASCAR event that will put winners in a NASCAR simulator.

?Our business is based in Pittsburgh and Allegheny County. We?re supported by the local community in a very significant way,? he says.

Statewide

A major decision for the Gaming Control Board will be awarding the license for a second casino in Philadelphia. Six companies are vying for the state?s last Category 2 license, which allows a stand-alone casino with up to 5,000 slot machines and 250 table games.

Although Pennsylvania appears to have replaced New Jersey as the No. 2 gambling states, it faces competition from expansion in New York, Massachusetts, Maryland and elsewhere.

The state Gaming Control Board will see that the approval process for new games is quick and efficient, a spokesman says. The board also notes that several casinos are adding entertainment and conference venues, hotels and additional restaurants.

Nationwide

Online gambling will remain the No. 1 topic. Supporters of federal legislation authorizing legal online poker pulled the plug on their proposal in mid-December, while pledging to try again in 2013.

A 2011 U.S. Department of Justice ruling says states may offer online games within their borders. Nevada has authorized operators of online poker site that are expected to begin operations this year, and Delaware seems poised to offer online slots as well as poker, roulette, blackjack and other games.

Last week, New Jersey?s Legislature approved allowing online versions of any game offered in Atlantic City casinos. The bill was sent to Gov. Chris Christie.

California and other states are exploring legalization of online gambling.

Reaction to death of Norman Schwarzkopf

Reaction to the death Thursday of retired Gen. H. Norman Schwarzkopf:

___

"Barbara and I mourn the loss of a true American patriot and one of the great military leaders of his generation. A distinguished member of that 'Long Gray Line' hailing from West Point, Gen. Norm Schwarzkopf, to me, epitomized the 'duty, service, country' creed that has defended our freedom and seen this great nation through our most trying international crises. More than that, he was a good and decent man ? and a dear friend. Barbara and I send our condolences to his wife, Brenda, and his wonderful family." ? former President George H.W. Bush.

___

"With the passing of General H. Norman Schwarzkopf, America lost a great patriot and a great soldier. Norm served his country with courage and distinction for over 35 years. The highlight of his career was the 1991 Persian Gulf War, Operation Desert Storm. 'Stormin' Norman' led the coalition forces to victory, ejecting the Iraqi Army from Kuwait and restoring the rightful government. His leadership not only inspired his troops, but also inspired the nation. He was a good friend of mine, a close buddy. I will miss him. My wife, Alma, joins me in extending our deepest condolences to his wife, Brenda, and to her family." ? former Secretary of State Colin Powell.

Hammocks Trading Company restaurant review, Sandy Springs

$$

$$

In our Internet-driven age of information saturation, being a critic can be tricky.

To remain completely devoid of preconceptions after reading first-responder blog posts or crowd-sourced reviews often requires conscious effort, which is why I always try to avoid over researching potentially reviewable restaurants. Now more than ever, objectivity is a skill. Walking in the door with inflated expectations is often unfair to the chef, while believing every online nitpicker can make a mediocre meal pleasantly surprising.

When I decided to try Hammocks Trading Company in Sandy Springs, I had no expectations to overcome, knowing nothing about the restaurant or the chef. I knew it was seafood, but that?s it.

I had no idea that executive chef and partner William Sigley spent seven years in Las Vegas working under the likes of Todd English and Wolfgang Puck before moving to Atlanta to lead the kitchens of Aquanox, Aja, and Bone?s. Nor was I

aware that co-owner and front-of-the-house manager Jason Sheetz was once general manager of Twist and area director of other Here 2 Serve restaurants such as Prime and Goldfish. I was a blank slate.

As I first enter the stand-alone building on Roswell Road, however, the snap judgments begin. Wood-paneled walls of white and pastel blue evoke memories of every Gulf Coast beach condo I?ve rented, punctuated by the namesake hammocks scattered across the ceiling. The feel is coastal Carolina beach shack, where a round or two of Jimmy Buffet tunes is moments away from erupting out of a hidden jukebox.

But as we sit for our first pre-meal cocktail, where I expect overly sweet margaritas, instead I find sips of an eye-poppingly delicious Horse?s Neck ($8). I find myself ordering a second round of the crisp bourbon and ginger beer libation, enjoying an acidic kick of the ginger-lime syrup. Following that up with the swarthy El Diablo ($8), a smoky blend of mezcal, lime, creme de cassis and ginger beer, and I?m realizing that there is more to this place than I first suspected.

The cuisine is primarily coastal seafood, with Baja influences, and the heavy focus on small plates makes this a meal great for sharing with friends. A much more casual menu than he?s crafted at previous restaurants, Sigley?s experience in fine dining shines through in finesse and balanced flavors.

Many of the expected standbys make the menu, like honkin? peel and eat shrimp ( $7/half-dozen) and steamed oysters ($7/half-dozen), but few true beach dives offer something as subtle as Sigley?s spicy and sour pickled shrimp atop cornmeal fried green tomato ($6.50).

Bivalve fans can leave with a full stomach and a pile of half shells, as I didn?t find a single oyster I didn?t enjoy. Like all the seafood I taste here, the freshness is obvious while we slurp down a dozen raw ($13). But the grilled oysters with simple melted compound barbecue butter ($15/dozen) can turn a raw-only enthusiast like myself into a convert.

But while I enjoy our bowl of steamed mussels ($7.50) well enough, I?m left wishing for a more developed white wine and garlic broth than what arrives. The flavors are there but fall a little flat for my liking. Perhaps if the ?grilled bread? was more of a buttery charred sponge of baguette or ciabatta instead of the thin, crunchy wafers that accompany the dish, the under seasoned broth would be less of an issue. The shortcoming of the mussels stand out even more prominently next to Sigley?s wonderfully unrefined but deeply flavorful bowl of chef?s fish soup ($15.50). Each spoonful goes down quickly, with the rich shellfish broth stealing the show.

Some dishes stay true to the Southern coastal cuisine, such as a bowl of thick shrimp and crab gumbo ($6.50), and others blend those flavors with a touch of California. A south coast ceviche, with vinegary hunks of scallop, shrimp and fish, accented with mango, cilantro, red onion and fresh jalapeno, is one part Baja, one part Charleston. And Sigley adds some very successful sophistication to a plate of perfectly cooked, buttery scallops

atop butternut squash drizzled with black truffle and an apple cider reduction. This remains the biggest crowd pleaser of my visits.

In some ways, Hammocks presents a conundrum. On the surface, you have a casual, reasonably priced seafood kitchen, a place to relax with friends and enjoy the familiar dishes of the Southern coast. But, on the other, Sigley laces his menu with several pleasant surprises, and more than a few mouthfuls that showcase his depth of skill to the point where they almost seem out of place here.

Even in his weakest showings, Sigley?s worst dishes here are pretty decent, with the majority of the menu consistently better than most in its class, peppered with flashes of brilliance. Sure, there are certainly better overall plates of refined seafood to be had in the city if you are looking for splurge, but if it is a laid-back and affordable seafood feast you are after, Hammocks is worth a drive.

Heavy Snow Blankets Southern Illinois

FIRST PERSON | WEST FRANKFORT, Ill. -- In a year of severe weather, including a drought that left the local area devastated, a winter storm has so far dumped six inches of snow with more still falling here in southern Illinois.

As of 8 a.m. local time, there was still a blizzard watch for the area until noon with snow in the forecast until at least 4 p.m. Authorities are advising everyone except for emergency workers to stay off of the roads until the storm passes.

The snow began falling locally a little after 10 p.m., though the winds, gusting up to 35mph, had begun in the early evening. The heaviest snow began to fall at 2 a.m. Visibility was so poor that venturing away from the house would leave you in a swirling haze of snow with winds inhibiting your ability to find your way back.

While visibility has improved considerably, the blowing snow alone makes for hazardous driving conditions. I live on a normally busy street and there are no signs anyone has attempted to venture out thus far.

There are currently no reports of power outages or downed limbs. The best course of action at this point is to stay inside and allow nature to take its course and then allow clean-up workers to do their jobs.

Local message boards have been speculating that the local area is in for a winter with far more snow than usual. The National Weather Service has projected that the winter will be colder than normal and that the area should be out of the drought before the farmers start spring planting. This doesn't bode well in an area that is 29 inches low on precipitation due to the drought but only averages eight inches of snow each winter!

Amazon deforestation brings loss of microbial communities

Dec. 24, 2012 ? An international team of microbiologists led by Klaus N?sslein of the University of Massachusetts Amherst has found that a troubling net loss in diversity among the microbial organisms responsible for a functioning ecosystem is accompanying deforestation in the Amazon rainforest.

N?sslein, an expert in tropical rain forest microbial soil communities, says, "We found that after rainforest conversion to agricultural pastures, bacterial communities were significantly different from those of forest soils. Not only did the pasture soils show increased species numbers, these species were also less related to one another than in rainforest soil. This is important because the combination of lost forest species and the homogenization of pasture communities together signal that this ecosystem is now a lot less capable of dealing with additional outside stress."

He and colleagues studied a large farm site over the past four years at the frontier where farmers drive agriculture into pristine rainforest in Rondonia, Brazil, to convert rainforest to agricultural use. Findings in part validated previous research showing that bacteria in the soil became more diverse after conversion to pasture. However, in its fourth year, their study overcame limitations of earlier investigations to show that changes in microbial diversity occurred over larger geographic scales. Results appear in the current issue of Proceedings of the National Academy of Sciences.

In addition to N?sslein at UMass Amherst, the research group includes first author Jorge Rodrigues at the University of Texas at Arlington with Brendan Bohannan at the University of Oregon, James Tiedje at Michigan State University, and others at the University of Sao Paulo. Lead investigators N?sslein and Rodrigues emphasize that the study is an equal collaboration among the four research groups.

Findings do not support earlier study conclusions, instead they show that the loss of restricted ranges for different bacteria communities results in a biotic homogenization and net loss of diversity overall. Scientists worry that the loss of genetic variation in bacteria across a converted forest could reduce ecosystem resilience. The researchers hope their work will provide valuable data to those making decisions about the future of the Amazon rainforest.

Biologist and first author Jorge Rodrigues of the University of Texas at Arlington adds, "We have known for a long time that conversion of rainforest land in the Amazon for agriculture results in a loss of biodiversity in plants and animals. Now we know that microbial communities which are so important to the ecosystem also suffer significant losses."

As N?sslein and colleagues point out, the Amazon represents half of the world's rainforest and is home to one-third of Earth's species, yet the Amazon has one of the highest rates of deforestation. Agriculture is one of the largest and most dynamic parts of Brazil's economy, so dealing with standing rainforests in the tropics will be tricky, but nevertheless, it is vital that the issue is tackled."

Rodrigues says he and colleagues are currently compiling findings about the potential for recovery of the microbial diversity after pastureland is abandoned and returned to "secondary forest." At the same time, N?sslein and colleagues are leading an effort to investigate how the redundancy of functions provided by soil microbes provides resilience to the effects of agricultural land use change to support a stressed ecosystem to recover stability.

"Whether bacterial diversity will completely recover from ecosystem conversion will depend in part on whether the taxa lost due to conversion are truly locally extinct or whether they are present in the pasture sites but of such low abundance that they are undetectable in our study," the authors write.

This work was supported by grants from the USDA National Institute of Food and Agriculture and the Research Support Foundation of the State of S?o Paulo.

Evidence contradicts idea that starvation caused saber-tooth cat extinction

In the period just before they went extinct, the American lions and saber-toothed cats that roamed North America in the late Pleistocene were living well off the fat of the land.

That is the conclusion of the latest study of the microscopic wear patterns on the teeth of these great cats recovered from the La Brea tar pits in southern California. Contrary to previous studies, the analysis did not find any indications that the giant carnivores were having increased trouble finding prey in the period before they went extinct 12,000 years ago.

The results, published on Dec. 26 in the scientific journal PLOS ONE, contradicts previous dental studies and presents a problem for the most popular explanations for the Megafaunal (or Quaternary) extinction when the great cats, mammoths and a number of the largest mammals that existed around the world disappeared.

"The popular theory for the Megafaunal extinction is that either the changing climate at the end of the last Ice Age or human activity or some combination of the two killed off most of the large mammals," said Larisa DeSantis, assistant professor of earth and environmental sciences at Vanderbilt, who headed the study. "In the case of the great cats, we expect that it would have been increasingly difficult for them to find prey, especially if had to compete with humans. We know that when food becomes scarce, carnivores like the great cats tend to consume more of the carcasses they kill. If they spent more time chomping on bones, it should cause detectable changes in the wear patterns on their teeth."

In 1993, Blaire Van Valkenburgh at UCLA published a paper on tooth breakage in large carnivores in the late Pleistocene. Analyzing teeth of American lions, saber-tooth cats, dire wolves and coyotes from La Brea, she found that they had approximately three times the number of broken teeth of contemporary predators and concluded, "...these findings suggest that these species utilized carcasses more fully and likely competed more intensely for food than present-day large carnivores."

The latest study uses a new technique, called dental microwear texture analysis (DMTA), developed by co-authorPeter Ungar at the University of Arkansas. It uses a confocal microscope to produce a three-dimensional image of the surface of a tooth. The image is then analyzed for microscopic wear patterns. Chowing down on red meat produces small parallel scratches. Chomping on bones adds larger, deeper pits. Previous methods of dental wear analysis relied on researchers to identify and count these different types of features. DMTA relies on automated software and is considered more accurate because it reduces the possibility of observer bias.

DeSantis and Ungar, with the assistance of Blaine Schubert from East Tennessee State University and Jessica Scott from the University of Arkansas, applied DMTA to the fossil teeth of 15 American lions (Panthera atrox) and 15 saber-tooth cats (Smilodon fatalis) recovered from the La Brea tar pits in Los Angeles.

Their analysis revealed that the wear pattern on the teeth of the American lion most closely resembled those of the present-day cheetah, which actively avoids bones when it feeds. Similarly, the saber-tooth cat's wear pattern most closely resembled those of the present-day African lion, which indulges in some bone crushing when it eats. (This differs from a previous microwear study using a different technique that concluded saber-tooth cats avoided bone to a far greater extent.)

The researchers examined how these patterns changed over time by selecting specimens from tar pits of different ages, ranging from about 35,000 to 11,500 years ago. They did not find any evidence that the two carnivores increased their "utilization" of carcasses throughout this period. If anything, their analysis suggests that the proportion of the carcasses that both kinds of cats consumed actually declined toward the end.

The researchers acknowledge the high rate of tooth breakage reported in the previous study, but they argue that it is more likely the result of increased breakage when taking down prey instead of when feeding.

"Teeth can break from the stress of chewing bone but they can also break when the carnivores take down prey," DeSantis pointed out. Species like hyenas that regularly chew and crack bones of their kills are as likely to break the rear teeth they use for chewing as their front canines. Species like the cheetah, however, which avoid bones during feeding are twice as likely to break canines than rear teeth. This suggests that they are more likely to break canines when pulling down prey.

The researchers report that previous examinations of the jaws of the American lions and saber-tooth cats from this period found that they have more than three times as many broken canines and interpret this as additional evidence that supports their conclusion that most of the excess tooth breakage occurred during capture instead of feeding.

In addition, the researchers argue that the large size of the extinct carnivores and their prey can help explain the large number of broken teeth. The saber-toothed cats were about the size of today's African lion and the American lion was about 25 percent larger. The animals that they preyed upon likely included mammoths, four-ton giant ground sloths and 3,500-pound bison.

Larger teeth break more easily than smaller teeth. So larger carnivores are likely to break more canine teeth when attempting to take down larger prey, the researchers argue. They cite a study that modeled the strength of canine teeth that found the canines of a predator the size of fox can support more than seven times its weight before breaking while a predator the size of lion can only support about four times its weight and the curved teeth of the saber-toothed cats can only support about twice its weight.

"The net result of our study is to raise questions about the reigning hypothesis that "tough times" during the late Pleistocene contributed to the gradual extinction of large carnivores," DeSantis summarized. "While we can not determine the exact cause of their demise, it is unlikely that the extinction of these cats was a result of gradually declining prey (due either to changing climates or human competition) because their teeth tell us that these cats were not desperately consuming entire carcasses, as we had expected, and instead seemed to be living the 'good life' during the late Pleistocene, at least up until the very end."

The researchers report that previous examinations of the jaws of the American lions and saber-tooth cats from this period found that they have more than three times as many broken canines and interpret this as additional evidence that supports their conclusion that most of the excess tooth breakage occurred during capture instead of feeding.

In addition, the researchers argue that the large size of the extinct carnivores and their prey can help explain the large number of broken teeth. The saber-toothed cats were about the size of today's African lion and the American lion was about 25 percent larger. The animals that they preyed upon likely included mammoths, four-ton giant ground sloths and 3,500-pound bison.

Larger teeth break more easily than smaller teeth. So larger carnivores are likely to break more canine teeth when attempting to take down larger prey, the researchers argue. They cite a study that modeled the strength of canine teeth that found the canines of a predator the size of fox can support more than seven times its weight before breaking while a predator the size of lion can only support about four times its weight and the curved teeth of the saber-toothed cats can only support about twice its weight.

"The net result of our study is to raise questions about the reigning hypothesis that "tough times" during the late Pleistocene contributed to the gradual extinction of large carnivores," DeSantis summarized. "While we can not determine the exact cause of their demise, it is unlikely that the extinction of these cats was a result of gradually declining prey (due either to changing climates or human competition) because their teeth tell us that these cats were not desperately consuming entire carcasses, as we had expected, and instead seemed to be living the 'good life' during the late Pleistocene, at least up until the very end."

Over the fiscal cliff: What kind of landing?

WASHINGTON (AP) ? Efforts to save the nation from going over a year-end "fiscal cliff" were in disarray as lawmakers fled the Capitol for their Christmas break. "God only knows" how a deal can be reached now, House Speaker John Boehner declared.

President Barack Obama, on his way out of town himself, insisted a bargain could still be struck before Dec. 31. "Call me a hopeless optimist," he said.

A look at why it's so hard for Republicans and Democrats to compromise on urgent matters of taxes and spending, and what happens if they fail to meet their deadline:

___

NEW YEAR'S HEADACHE

Partly by fate, partly by design, some scary fiscal forces come together at the start of 2013 unless Congress and Obama act to stop them. They include:

? Some $536 billion in tax increases, touching nearly all Americans, because various federal tax cuts and breaks expire at year's end.

? About $110 billion in spending cuts divided equally between the military and most other federal departments. That's about 8 percent of their annual budgets, 9 percent for the Pentagon.

Hitting the national economy with that double whammy of tax increases and spending cuts is what's called going over the "fiscal cliff." If allowed to unfold over 2013, it would lead to recession, a big jump in unemployment and financial market turmoil, economists predict.

___

WHAT IF THEY MISS THE DEADLINE?

If New Year's Day arrives without a deal, the nation shouldn't plunge onto the shoals of recession immediately. There still might be time to engineer a soft landing.

So long as lawmakers and the president appear to be working toward agreement, the tax hikes and spending cuts could mostly be held at bay for a few weeks. Then they could be repealed retroactively once a deal was reached.

The big wild card is the stock market and the nation's financial confidence: Would traders start to panic if Washington appeared unable to reach accord? Would worried consumers and businesses sharply reduce their spending? In what could be a preview, stock prices around the world dropped Friday after House Republican leaders' plan for addressing the fiscal cliff collapsed.

Federal Reserve Chairman Ben Bernanke has warned lawmakers that the economy is already suffering from the uncertainty and they shouldn't risk making it worse by blowing past their deadline.

___

WHAT IF THEY NEVER AGREE?

If negotiations between Obama and Congress collapse completely, 2013 looks like a rocky year.

Taxes would jump $2,400 on average for families with incomes of $50,000 to $75,000, according to a study by the non-partisan Tax Policy Center. Because consumers would get less of their paychecks to spend, businesses and jobs would suffer.

At the same time, Americans would feel cuts in government services; some federal workers would be furloughed or laid off, and companies would lose government business. The nation would lose up to 3.4 million jobs, the Congressional Budget Office predicts.

"The consequences of that would be felt by everybody," Bernanke says.

___

THE TAXES

Much of the disagreement surrounds the George W. Bush-era income tax cuts, and whether those rates should be allowed to rise for the nation's wealthiest taxpayers. Both political parties say they want to protect the middle-class from tax increases.

Several tax breaks begun in 2009 to stimulate the economy by aiding low- and middle-income families are also set to expire Jan. 1. The alternative minimum tax would expand to catch 28 million more taxpayers, with an average increase of $3,700 a year. Taxes on investments would rise, too. More deaths would be covered by the federal estate tax, and the rate climbs from 35 percent to 55 percent. Some corporate tax breaks would end.

The temporary Social Security payroll tax cut also is due to expire. That tax break for most Americans seems likely to end even if a fiscal cliff deal is reached, now that Obama has backed down from his call to prolong it as an economic stimulus.

___

THE SPENDING

If the nation goes over the fiscal cliff, budget cuts of 8 percent or 9 percent would hit most of the federal government, touching all sorts of things from agriculture to law enforcement and the military to weather forecasting. A few areas, such as Social Security benefits, Veterans Affairs and some programs for the poor, are exempt.

___

THERE'S MORE AT STAKE

All sorts of stuff could get wrapped up in the fiscal cliff deal-making. A sampling:

? Some 2 million jobless Americans may lose their federal unemployment aid. Obama wants to continue the benefits extension as part of the deal; Republicans say it's too costly.

? Social Security recipients might see their checks grow more slowly. As part of a possible deal, Obama and Republican leaders want to change the way cost-of-living adjustments are calculated, which would mean smaller checks over the years for retirees who get Social Security, veterans' benefits or government pensions.

? The price of milk could double. If Congress doesn't provide a fix for expiring dairy price supports before Jan. 1, milk-drinking families could feel the pinch. One scenario is to attach a farm bill extension to the fiscal cliff legislation ? if a compromise is reached in time.

? Millions of taxpayers who want to file their 2012 returns before mid-March will be held up while they wait to see if Congress comes through with a deal to stop the alternative minimum tax from hitting more people.

___

CALL THE WHOLE THING OFF?

In theory, Congress and Obama could just say no to the fiscal cliff, by extending all the tax cuts and overturning the automatic spending reductions in current law. But both Republicans and Democrats agree it's time to take steps to put the nation on a path away from a future of crippling debt.

Indeed, the automatic spending cuts set for January were created as a last-ditch effort to force Congress to deal with the debt problem.

If Washington bypassed the fiscal cliff, the next crisis would be just around the corner, in late February or early March, when the government reaches a $16.4 trillion ceiling on the amount of money it can borrow.

Boehner says Republicans won't go along with raising the limit on government borrowing unless the increase is matched by spending cuts to help attack the long-term debt problem. Failing to raise the debt ceiling could lead to a first-ever U.S. default that would roil the financial markets and shake worldwide confidence in the United States.

To avoid that scenario, Obama and Boehner are trying to wrap a debt limit agreement into the fiscal cliff negotiations.

___

SO WHAT'S THE HOLDUP?

They're at loggerheads over some big questions.

Obama says any deal must include higher taxes for the wealthiest Americans. Many House Republicans oppose raising anyone's tax rates. Boehner tried to get the House to vote for higher taxes only on incomes above $1 million but dropped the effort when it became clear he didn't have the votes.

Republicans also insist on deeper spending cuts than Democrats want to make. And they want to bring the nation's long-term debt under control by significantly curtailing the growth of Medicare, Medicaid and Social Security ? changes that many Democrats oppose.

Obama, meanwhile, wants more temporary economic "stimulus" spending to help speed up a sluggish recovery. Republicans say the nation can't afford it.

___

IT'S NOT JUST WASHINGTON

Seems like they could just make nice, shake hands and split their differences, right?

But there's a reason neither side wants to give ground. The two parties represent a divided and inconsistent America. True, Obama just won re-election. But voters also chose a Republican majority in the House.

Republican and Democrats alike say they are doing what the voters back home want.

Neither side has a clear advantage in public opinion. In an Associated Press-GfK poll, 43 percent said they trust the Democrats more to manage the federal budget deficit and 40 percent preferred the Republicans. There's a similar split on who's more trusted with taxes.

About half of Americans support higher taxes for the wealthy, the poll says, and about 10 percent want tax increases all around. Still, almost half say cutting government services, not raising taxes, should be the main focus of lawmakers as they try to balance the budget.

When asked about specific budget cuts being discussed in Washington, few Americans express support for them.

___

THE COUNTDOWN

Time for deal-making is short, thanks to the holiday and congressional calendars. Some key dates for averting the fiscal cliff:

? Lawmakers aren't expected to return to the Capitol until Thursday, leaving less than a week to vote on a compromise before year's end.

? Obama and his family also left town for a Christmas vacation in Hawaii. The president said because the fiscal cliff was still unresolved, he would return to Washington this week.

? If lawmakers reach Dec. 31 without a deal, some economists worry that the financial markets might swoon.

? The current Congress is in session only through noon Eastern time on Jan. 3. After that, a newly elected Congress with 13 new senators and 82 new House members would inherit the problem.
