Wont by any of the 3...
Wont be Rubio, he has already said hes not interested in the job. He's ambitious, he doesn't want a dead-end job like VP.
Wont be Christie either, as he brings nothing that helps Romney, hes also extremely unpopular in his home state and will undoubtably LOSE reelection. Why would Romney want to teamup with someone so unpopular from a State thats going to vote Democrat anyway?
And the fact is people do not want a Fat Man for president. Its unfair, I agree, but people ARE judged on appearances that's just a sad fact. Christie just doesn't look physically presidential.
And Rice? Forget it.
A. She's black (the GOP hates blacks)
B. She's a woman (the GOP hates women)
C. She is NOT a radical right conservative nor does she pretend to be (unlike Romney).
D. She was chief apologist for the Bush Administration. Nobody wants that.
E. She will get exactly 3 Black Votes. Not 3%, 3 actual black votes. Those being: Herman Cain, Clarence Thomas, and her own. That's it.
