The big loser of this debate is Tom Brokaw. He didn't enforce the rules, he didn't press the candidates to actually answer the question like the previous moderator tried, and he picked mostly boring questions taking all the fun out of a town hall style debate.
Obama's class warfare credo is definitely a clear and visible difference between the two candidates' economic philosophies. Personally I don't think it is correct regardless of the current economic conditions, but some or perhaps many Americans like polish and campaign promises over service to country and experience. Obama is a better speaker than McCain, and he only had to tie to come out as the winner, so he probably is the winner.
