The responsibility for the most partisan atmosphere is Washington D.C. history goes to President Barack Obama, according to Sen. John McCain. "[Obama] said there would be a change in the climate in Washington. There's been a change. It's more partisan. It's more bitterly divided than it's been," McCain told Fox News' Chris Wallace.

A few Republicans have participated in crafting major legislation during Obama's first year in office. Three Republican Senators voted for the stimulus bill and Republican Sen. Olympia Snowe voted for the health care bill coming out the Senate finance committee.

But for the most part, Republicans have voted together to block Democrats' attempts to pass legislation more often than any Congress in history. On December 18, Republicans broke the modern-day record for the most filibusters in history, according to Campaign for America's future.
