Sarah Palin runs in 2012

How well does she do if she runs in the primary???

This would prevent the rotating anti-Romney candidates from rising in the polls. Bachmann, Perry, and Cain would do as well as Lindsey Graham did in 2016.

She's Romney's primary arch nemesis throughout the primaries, like darklordoftech pointed out, but ultimately falls short. It wouldn't be for nought, however, because she would be in a great position to force Romney to be more combative- IMO, an explicitly Tea Party Romney carries Florida, outperforming ours.

If she won the nomination, she'd carry all the Romney states except NC.
