President Barack Obama cut short his Hawaiian vacation, and Congress is on call through the holidays as the nation heads to the year-end "fiscal cliff."
House Speaker John Boehner said "God only knows" how a deal can be reached now, while Obama insisted a bargain could still be struck before Dec. 31. "Call me a hopeless optimist," he said. (Read More: Obama: 'I Still Think We Can Get This Done')
Here's 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.
