Interesting stuff: this site, taking today's new polls into account, says Kerry will win the Electoral vote 274-264 while losing the popular vote, narrowly, to Bush.
There would be a certain poetic justice if this were to occur. Obviously still a ways to go yet. I don't neccesarily buy some of today's polls (Kerry losing NJ, winning IL by only 4, etc.). And of course this analysis is just theoretical.
