When the Republican primary was still being contested, I remember countless Republicans saying they would not support McCain even if he won the primary. That they wouldn't vote or would vote for Clinton over McCain. I suspect most of them will, alas, fall in with their party and vote Republican even though they dislike McCain.

I'll probably here the same thing I've heard for multiple elections... I hate the candidate, but I can't let a Democrat win, because it'd be even worse! Oh yes, sure, the Republican has been even worse on what I care about than anyone before now, but now that the precedent is set, a Democrat would be even worse, plus this Republican supports some other issue I care about that the Democrats don't!

I expect many people who vote Democrat will do the same thing. I already know many people whose preferred candidate is out or never was a Democrat to start with who will vote Democrat because well, the Republican is worse. I'm one of them. Obama is my second choice and I don't like Clinton anymore. But I'd vote for either of them if they were the Dem candidate. I hate McCain.
