All Romney and his big money can do is chase strong rivals out of the race. When that happens, the party gets stuck with leftovers like Michele Bachmann, Herman Cain and the Newter -- candidates who just want to hog the spotlight, not build the party. For 2016, think Dr. Ben Carson.
In the end, the contest didn't help Romney, either. Forced to move ever rightward, Romney shied away from his tenure as a competent, moderate Massachusetts governor. He can't go home again.
