As far as I’m concerned:
- Obama vs. McCain: 4:6 and …
- Biden vs. Palin: 7:3 …
… with 10 points to distribute per debate.
I was surprised how calm and clear McCain talked, and how messy Obama’s talk got from time to time (I had contrary expectations). Then again, Biden was clearly ahead of Palin; she had learned most of her statements by heart (as did Biden, I reckon, but you didn’t see it that well), she dodged critital questions many times, and simply wasn’t as genuine and frank as Biden.
I also have to add that my opinion is not shared by the media; all reports I’ve read (around 5 for each debate) state 5:5 for both debates.
