I must admit that I was glued to my seat watching the Redskins put up a good fight against the Broncos last night. So, I only watched the last 15 minutes of the debate between Kilgore and Kaine. The lasting impression that I'll have is of Kaine's creepy left eyebrow. It freaked out my wife too. I've got to find a picture of it.
For some analysis of substance, though they mention the eyebrow too, start at Bacon's Rebellion.
