text:  Now here's Chuck Todd on Joe Biden's performance tonight. Look, that Joe Biden was very disciplined. He needed to push back on the notion that he talked too much. Joe Biden, the vice presidential debater, I thought was a really effective debater, both against Paul Ryan and against Sarah Palin. He was very disciplined. He's really good at moving message. But this version is not the same guy. I don't think he's as nimble.
