I think that although he's usually a good speaker, he kind of stumbled (well, stumbled for *him*) through this one. He got a few facts about J. K. Rowling wrong (things anybody could realize, like mispronouncing her last name), and I thought he kind of talked about the same thing the whole time, just rephrasing constantly. I may be biased, though, having my harcore Republican father in the house :)
If I ever find my actual piece, I'll post it, but knowing me, it'll take a year. Blah. Now you know what I thought.
