Remember George Bush lost the first two debates with Senator Kerry four years ago and then took an agressive, get in your face, stance for the third debate, winning the debate and then winning the election by over 3,000,000 votes the largest winning percentage in American election history.
McCain's voice cracked a couple of times, but I think he did well to keep pounding on the subject that Obama is not ready to take the helm of a country this big.
Obama will become a better senator after this election so he can have a better chance in 2012 with at least four more years of experience he should do much better (not just in the polls, but in the actual race), but so will Mrs Clinton all the while saying, "Obama should've chose me for a running mate"
