Just some food for thought:
If Gore had won the presidency in 2000, and presumably re-election in 2004, we would have now been more than likely looking at an "inevitable" Lieberman presidency. At least, Lieberman (as Gore's VP) would surely have been the front runner for the Dem. nomination.
Of course, nobody can say what might have happened differently should Gore have been president. But as the fight for the Democratic nomination is becoming uglier, lets all at least be thankful we have the candidates we do, and that Lieberman isnt one of them.
