THIS is what Sarah AND NEWT GINGRICH have in plan in Tampa.
There hasn’t been a sitting President since before FDR who won reelection after experiencing a serious primary challenge.
The threat of such, and laying it out now, is IMHO a valid and workable check on Mittens returning to his old ways should Conservatives hold their noses and support him in an ABO scenario. So long as the one(s) making the threat are trusted Conservatives and there are other clear indicators (like who he picks as his veep) that he plans to go against his past track record and govern from the right.
