No impression on me, really. I'm even more disillusioned with McCain than I expected to be though, he's really getting on my nerves with hammering his character into people's minds - it's getting old John. It worked well at the convention but it's really wearing out now, and you can't keep talking about how good a guy you are to win a debate.
Obama has bigger teeth than I thought, but he's biting in the wrong direction and not taking enough of a bite at McCain either.
So,

for both so far.
