McCain picked Palin specifically because it would draw fire from himself. It also has the side effect of drawing both the super-conservative crowd and the "anyone but Obama" ex-Hillary supporters (although risking losing the moderates such as myself).
Personally, even with the VP picks laid out, I still don't care who wins. So long as the winner doesn't try to ban video games (as Hillary, a Jack Thompson supporter, would have doubtless tried to do), I'm fine with it. With most substantive issues, I can't really favor either Obama or McCain (although I'm starting to lean towards Obama on the economy).
