When they wouldn't have to be obstructionists if Obama would actually try to meet them somewhere in the middle. Honestly despite Obama's talk he's probably the least flexible president in recent history.
Excuse me? What are you smoking?
Bush and Clinton both got things done with congresses in the opposite party because those congresses were working with them -- both the republican congress with Clinton and the democratic congress with Bush. It's fact, not opinion, that this congress has put up more stumbling blocks against this president in the past 2 years than at any other time in history.
For Thor's sake, the republicans routinely vote AGAINST bills that they themselves authored just because Obama decides he likes them. That's happened at least a half-dozen times this year. The republicans in congress have said out loud that they are purposely trying to destroy this country under Obama's watch so that he'll take the blame. If that's not obstructionist I don't know what is.
