The numbers demonstrate just how poorly Bush did in the debate. He wasn't even mediocre; he was awful. And I think many conservatives are focusing on what was said, instead of what they saw. Whether its right or wrong, many women judge a debate on appearances, and Bush was terrible. I saw a timid, tongue-tied, ill-prepared man. He appeared as though he was incapable of defending himself. Anyone who didn't know Kerry would attack him so profusely must have been asleep at the switch. Kerry was behind in the polls with nothing to lose; it was obvious he was going to come out swinging. And Bush just rolled over. It was an indefensible performance.
Kerry's biggest edge is in performing better in the debates than was expected. He did not come across as unlikable when most people were convinced that he would.
Bush did not necessarily "blow it", Kerry just did what he needed to do to get right back in the race. Because of that, this election is going to go right down to the wire once again.
