I believe you may be right. Al Gore's been dreaming of the White House since he was a child. I would not count him out yet, and if Hillary runs to the center, Gore can keep screaching on the left and carry the fringe in the primaries.
I don't think he'll win though. Hillary running in the primaries will bring in very high turnout (for a primary) and she'll carry it.
But I think Gore does despise the Clintons, and I wouldn't be surprised to see him try to torpedo her campaign.
But what record is Gore going to run on? He used to be a vice president that lost? What is on his resume lately except giving ranting shrieking speeches? Same thing with John Edwards. His resume says he is an out of work trail lawyer who also would have lost his senate seat had he not tried and failed to become vp?
