I think Condi would be better to start off as VP, but Dick Morris certainly thinks she is it.
Rudi/Rice?
Romney/Rice?
Rudi/George Allen?
McCain/Romney?
Too soon to tell....
For Condi to run, she would have to start just about now in starting a foundation to run with.
I don't see any indications or have read of any and it appears that she is maintaining that she doesn't want anything to do with it, which is probably a good idea.
I don't think she would be able to pull it off at the top of a ticket. She hasn't held an elective office. She hasn't been in any legislature or anything like that.
As a VP, it's possible, but I kinda don't think that will happen either.
