This is a bit of a complicated one, but let's say there's no 22nd Amendment and Clinton-Gore runs again and narrowly win in 2000, perhaps a bit cleaner due to Clinton's presence. How does the third term go, with 9/11 and the results? How do the duo look going into 2004? Does Clinton consider running for a fourth term? Is he still popular? Is the recession pushed off, sped up or as OTL? What happens to Gore? Assuming Bush-Cheney is still nominated in 2000, who are 2004's nominees?
To start off with, if Clinton had run again, he'd have won a landslide. He was immensely popular at the end of his second term, and he'd have curbstompped Shrub. Ooh, those debates would have been awesome, and W would have become little more than a historical footnote in the future.
As for everything that happened OTL, who knows. I don't think it's beyond the realm of possibility to say that perhaps the 9/11 plot might have been stopped by the intelligence services beforehand. The Bush transition team blew off the Clinton team's attempts to brief them on terror matters, and the flippant manner the treated the terror threat in the beginning months of their administration leads on to ponder what could have been...
As far as 2004, if things do go generally OTL, then you could see McCain's best chance as attaining the White House. Gore is Gore, a great, intelligent, homourous guy in a laid-back setting but a wonky and stiff politician. Maybe he doesn't even run, but the Democratic bench at the time wasn't terribly deep. Besides, 12 years is a long time for a single party to control the White House.
Should McCain win, then we will probably end up in 2008 at about the same place we did OTL. Considering the man never met a war he didn't want to fight, I see us entering the 2008 elections bogged down in foreign conflicts with no end in sight and an economy on the brink of collapse. All hail Madam President Hillary Clinton and Vice President Barack Obama
