I watched the whole thing last night, even though I was wishing it had started an hour earlier than it did. For the first time this year the debate was content oriented rather than filled with gotcha questions from moderators or petty name calling by the debaters. A nice change although it was a bit puzzling as to why any number of journalist types were tweeting how bored they were. I guess actual content isn't what our media really likes.
The one guy I did not like at all was John Kasich. He was constantly butting in, speaking in an angry tone, and very much appeared to be how a character on Saturday Night Live would portray him.
In the end, there are any number of people who did well and it's also obvious many of the candidates need to withdraw. Huckabee, Graham, Kasich, Pataki, Santorum, maybe even Rand Paul and Jindal. It's still very early in the game, though, so even with a lot of time, it would be better to narrow the field.
