The right has thrown down the gauntlet: rehabilitate Bush, to rehabilitate conservatism, and if they can't do that, sever Bush from conservatism.
The thing is, they just can't "sever Bush from conservatism." The entire conservative movement hung it all on Iraq. Huggy Bear is hanging it all on Iraq. At the moment Iraq is the conservative movement. There's nothing else. The only way to sever bush from conservatism is to sever conservatism from Iraq. And they can't.
