Third Debate: What's Going on Here?

Maybe it's just me, but I'm at a loss when considering that a large majority believe that John Kerry won the final debate last night. Perhaps it's just because the President gave such a weak performance on the first, so no one is giving him credit anymore. But I honestly think that he edged Kerry on the second debate and flat out won on the third. The President was at his absolute best last night, especially near the end. Even the talking heads basically gave him a win. Yet, voters believe that Kerry won by nearly the same margin as he did in the first debate. Something must certainly be wrong, either in the polling process or in the voting population. I'm not sure which it is but it's not good for the President.
