Biden knocked it out of the park, I thought. He didn't patronize and he obviously knows what the hell he's talking about. I'm really glad he didn't say anything stupid.
Palin didn't totally blow it, but she didn't answer any of the questions. She stuck to the talking points and didn't inject any of her own ideas or thoughts. Probably because she doesn't have any. I'm already tired of the folksy schtick.
So, overall I don't think this debate is gonna change anything poll wise, but Palin definitely saved her own skin.
