(WASHINGTON) -- President Obama returns from his Hawaiian holiday this week to a changed Washington where Republicans will control the House of Representatives.
But don't count on a new era of bipartisanship any time soon. Congress's new Republicans and old Democrats are already at war.
Lawmakers sparred Sunday during talk shows about the national debt, for starters. Even as the debt races toward $14 trillion, some Republicans said they would oppose extending the debt limit beyond the current $14.3 trillion, although such a move could shut down the government.
Republicans are threatening to cut off the ability of the government to borrow money unless spending goes back to where it was before the stimulus and before the banking bailout.
The fight over the national debt is on the horizon. More immediately, Republicans will start with health-care overhaul, signed into law last year after a bruising, lengthy legislative battle.
One of the first votes of the new Congress in 2011 will be an effort to repeal the health care bill Democrats passed in 2010. That repeal effort will likely fail in the Senate, which is still controlled by Democrats. But Republicans will then try to starve the bill of money.
The third line of attack will be investigations. The new Republican sheriff is Rep. Darrell Issa of California, who will chair the House committee in charge of government investigations. Issa has said he's planning a barrage of hearings on everything from Medicare fraud to the government's failure to prevent the BP oil spill.
