By way of Keith Olbermann, another Republican Senator, Gordon Smith of Oregon, is cutting and running from Bush's Iraq policy:

I, for one, am at the end of my rope when it comes to supporting a policy that has our soldiers patrolling the same streets in the same way, being blown up by the same bombs day after day. That is absurd. It may even be criminal. I cannot support that anymore. I believe we need to figure out how to fight the war on terror and to do it right. So either we clear and hold and build, or let's go home.

He also quotes Churchill: "The statesman who yields to war fever must realize that once the signal is given, he is no longer the master of policy but the slave of unforeseeable and uncontrollable events."
