Not saying he won't run again. But I just don't see him winning the Democratic Nomination again. Nor do I see Gore ever having a chance again. History has shown that once you lose a presidential election, you're presidential hopes are more or less finished. Yes there was Richard Nixon, but I think he was the exception to this rule.
In 1960 Richard Nixon actually won the Popular Vote (depending on how you count the "unpledged Democrat elector" votes in Alabama). Of course, so did Gore, but the recount killed him.
I think some new "superstars" will emerge on both sides between now and 2007. I mean, who outside of Texas even knew about George W in November 1996? I mentioned to people back in 1998 (or even 1999) that he could be our next president, and people looked at me like I was insane.
The people who want it most are going to make a name for themselves, or change their positions to conform to the party line. If Giulliani really wants the nod, he'll get more socially conservative, much as Dennis Kucinich mysteriously became Pro-Choice in 2002. Bill Frist may push his way into the spotlight.
I think the GOP Senators have very little chance as long as the GOP is the majority party. You get much more attention as part of the opposition. For this reason Russ Feingold could emerge as the front-runner. He would make an awesome candidate.
Bottom line: it's too early to tell right now.
