It seems unlikely. Bush would be lost without Cheney and won't let him go without a fight and Cheney gives me no indication that he intends to step down. I agree he won't run. Even if Cheney wanted to run, his health would be too much of an issue. I would guess the GOP IS worried about 08 in that regard but, as I've been saying, if this war isn't history by 08, it won't matter who the GOP candidate is or what he says.
