Well, I disagree. Even if Giuliani-Rice could get the nod, they would lose the general because evangelicals would sit out the election, unless both become fire-breathing cultural conservatives within the next four years!
There are alot of names on both sides that won't "get the nod". Hitlery will never get the south. Giuliani, Ahhhhnold, and probably even McCain couldn't get the south. It depends on what the choices are, of course, but I believe the die is set for a more conservative type to get the nod. The left got a woody for Obama, but he won't make it either. CBSNYT will go bonkers for him, but I can't see him get anywhere outside of the northeast. We probably haven't heard the names yet of the winners.
