Obviously not 'nobody', but if you look at Bush's approval ratings and use that as a judgment of how a vote would go, I wouldn't want those numbers.
If you think Bush vs Obama would have gone to Bush, I tend to disagree. I think Obama is much stronger candidate than Kerry or the Goracle, but part of that is built on the anti-bush platform that will work for this election. being anything un-bush will be enough to get votes from some people.
I for one voted for Bush, will almost certainly vote for McCain, but don't consider myself to be of any party. I vote heavily democrat locally, and tend to hate all partisan politics. I would say I'm conservatively liberal I guess.
