I like Biden and Ryan more than Obama and Romney right now. I mean seriously this debate is shitloads of feisty.
--- edit ---
That was one badass debate. Ryan's closing comments were dumb but I mean besides that I think both candidates REALLY brought their A-game to the party. And so did the moderator. I THINK that Biden might be considered the winner in some nominal sense because he was more memorable -- whether you like or complain about the laughing and his... hamming it up to an extent, he really established more of a persona up there.
Honestly though I think they both kind of won, at least with regards to what they each need to do.
