BOTH parties made the decision to go in based on the same evidence. This is Americas war - not Bush's war as the left would have you believe.
The evidence was quite faulty. I agree that it is America's war, not just Bush's. But Bush is the Commander in Chief. The thing about the left is that they would be against Bush no matter what he did or didn't do. I am against him for what he did. (but at least we got two good SCOTUS appointments out of it).
