Here’s a prediction:

Sometime next year, around April as the campaign really starts heating up, Republicans on the chopping block are going to start publicly and aggressively disagreeing with the president, even attacking him outright. It’s already apparent that he is a liability to the party, but right now they only smell smoke. When they start to see fire they’ll change their tune, because their political survival is on the line. The more they differentiate themselves from him, the better are their chances of making it to the next year’s feeding season. Then the Democrats will follow suit and finally stand up to Bush with the strength they should have used all along, and at that point, the public will have difficulty distinguishing which party is the anti-bush party and the Dems will have lost any (or at least most) advantage they may have had from being the ONLY party to try and slay the Bush hydra.

How to prevent this: Take drastic legislative action to end the war, to oppose bush. Speak plainly and strongly. Not a single dime more for anything other than withdrawal. Shut down the government, even, the way the Newt-led congress did in the 90s over far more trivial matters.
