Seriously, how does anyone get elected when they can't even say "nuclear" right? It's like nucleus, which presumably you learned in biology, the year before chemistry.
Palin did a nice job of not choking, but she didn't really say anything. It was mostly rhetoric, and very little policy. She's charming, sure, but she has no idea what's going on.
Biden surprised me. Can't say I really knew anything about him, but I was pleasantly surprised. He had his bouts of rhetoric as well, but he actually talked about what he and Obama would do if elected. He was remarkably a good portion of the time.
I think the analysts are probably right, that this won't change much.
