Michael Tomasky does an interesting analysis of the congressional support for Bush vs Obama. He discusses a number of high profile votes and crunches the numbers, coming up with this:

Here’s how it all adds up:

Average Democratic Senate support for Bush: 45.5 percent.
Average Democratic House support for Bush: 36.8 percent.
Average combined Democratic support for Bush: 41.1 percent.
Average Republican Senate support for Obama: 8.8 percent.
Average Republican House support for Obama: 2.7 percent.
Average combined Republican support for Obama: 5.75 percent.

It’s fairly clear that the “both sides do it” trope is nonsense. And to my eyes, knowing the kind of centrist and right wing policies the president has proposed, it shows just how radical the Republicans have become.
