Straight up! Gore is toast if he runs again. So's Clinton (Hillary). I don't see anyone on the horizon for the Dems.
But then, no one thought Bush had much of a chance either.
On the disagreement front, when Reagan ran for President in 1980, I remember hearing about the 11th Commandment: thou shalt not speak ill of a fellow Republican. And the joke about how a Democrat firing squad forms a circle.
I just thought it was interesting to see party discipline in action, that's all. They both do it.
