Paul Krugman explains bipartisanship 
But the part that really got me was Broder saying that we need “the best ideas from both parties.”
You see, this isn’t a brainstorming session — it’s a collision of fundamentally incompatible world views. If one thing is clear from the stimulus debate, it’s that the two parties have utterly different economic doctrines. Democrats believe in something more or less like standard textbook macroeconomics; Republicans believe in a doctrine under which tax cuts are the universal elixir, and government spending is almost always bad.
Obama may be able to get a few Republican Senators to go along with his plan; or he can get a lot of Republican votes by, in effect, becoming a Republican. There is no middle ground.
Bipartisanship is a joke. The sooner Obama learns this the better. It’s time for him to remind the Republicans that elections have consequences.
