I think that the people who despise Bush so much that they'd vote for just about anyone else rather than Bush are a fairly small minority of the voters in this election. I don't think most (or even relatively many) Americans see George W. Bush as a great villain.

If the Democrats nominate an ineffectual candidate, Bush will win. There really are quite a number of people who haven't yet made up their minds how they're going to vote in November.

[My Sci-Fi dream ticket is Lieberman/Clark. Two references in one!]
