McCain I thought blew his last chance. He's an ass-hole and it really shows. The reaction shots are going to kill him. The guy is 72 years old and he rolls his eyes and arches his eyebrows at things Obama says. Obama, by contrast, just smiles an open and engaging grin whenever McCain says something particularly stupid or mendacious.
Also he seemed to be running out of steam towards the end. That "generations of McCains" - - BIG mistake. The new voters, in fact anyone under 60, don't give a shit about bloodlines, it was just McCain's way of saying, "I'm superior to you [to Obama, sure, and to just about everyone else watching,] I'm superior to you and my family is superior to your family." Why doesn't he just say, "Vote for Obama, he's the better man?"
He seemed, in short, like a mean-spirited fool, a mean old man born with a silver spoon in his mouth and a completely unjustified sense of entitlement that is going to piss a lot of people off.
