Clinton vs. Obama

Seemingly, Obama and Clinton each have their own rock solid constituencies, and given the proportionate way delegates are determined, can either pull away?

It doesn't look like it.

Al Gore just might the difference maker. He's going to be under tremendous pressure to endorse a candidate. But I wonder if he's secretly wishing for a hopelessly deadlocked race, and yearning for a desperate Democratic party to come begging him to be their savior.
