Well if you look at the early polls already they are all going to Kerry pretty handily on who won the debate
To me this election has always kind of been compared to Carter Reagan in 80, you had a president who had a lot of negative situations to deal with, the country was split, but they did not know Reagan, Carter had painted him as a warmonger, someone not too smart
In the debate Reagan dispelled all of that, he showed he was a credible alternative
and in the last week of the election, it went from being tied to a significant 8 point win I believe by Reagan, if Kerry builds on this momentmum I can see those undecideds swinging his way, much like they did for Reagan in 1980
But still 2 more debates left, just don't see how Bush will fare better, because he lost he will be feeling the pressure and he just looked a little lost tonight
I'm thinking maybe it has to do with the fact that he has had the least number of press conferences of any president, he just didn't seem ready
