Pretty much every leading Republican politician in Idaho lined up, early, behind Romney. Easy at the time, given that he appeared to be the anointed one, and given his base of support among the LDS community in Idaho. But, I think that the tea party leaners in Idaho weren't so much behind him. Adam Graham, for example, is a Cain supporter, even now.
If Romney's campaign destructs, where will our Red Pols land? They'll support whoever the nominee eventually is, but if there is still a race going by the time of Idaho's presidential primary, you have to wonder.
Just remember, out of the billowing smoke and dust of tweets and trivia, emerged Gingrich.
