None of the Democrats "won," IMO. Obviously if you already favored one candidate, then you're probably going to think that one did well. Not going on what he said, but on his appearance and how he said things, I think Edwards came across the best, being so enthusiastic.
As far as Republicans...I think Huckabee did alright. I was very surprised he didn't bring up religion, since that seems to be one of his routes to his success thusfar. He seemed very positive. All of the others...meh. Ron Paul just seems so lost, more of a libertarian than anything.
And not to get personal with anyone on here, but I think anyone saying they will never vote "republican" or "democrat" is very short sighted. Putting those kinds of labels on people isn't always accurate. Giuliani supports abortion rights....isn't that anti-Republican? I don't think it's ever as black and white to say you will never vote one way or the other.
