By fucking up, I mean leaving himself open to attack by shifting stance on major issues (supporting the war for a while, then changing tune etc), which enabled people to go on about the "flip-flop" thing. I'm not saying he shouldn't have changed his mind, but politically things like that haven't worked well. Then there's his military record, which has turned from a strong point to a weak point. Despite all this, he's doing alright, and I'll be more than happy if he wins!
