I'm pretty surprised that McCain hasn't tried to move towards the center / left a lot more, since I think that's what he has to do to win.
Not that I'm complaining; he can keep running his campaign like Hillary did, primarily just going negative and trying to slam Obama for being popular.
To McCain: No, don't worry John, just because it didn't work when she tried it and you haven't been able to come up with anything better / dirtier, don't let that discourage you! Don't listen to those people that say so far your campaign is making you look like a jealous looser; they're just blinded by their cultist obsession with change...
