I saw Gore speak at Yale in 2004. I managed to be about 20 feet away from him. He is (and was) a man transformed--totally relaxed, funny, energetic, but also serious and impassioned--everything a candidate needs to be. Almost, dare I say it, Clintonesque. I think he would win in a landslide and hope he runs.
But more likely, a Hilary/Obama ticket. You heard it here first. Which would go up against McCain/Frist or whomever in the showdown of the century.
