DeMint: Palin Has Done More For GOP Than Anyone Since Reagan

Both DeMint and Palin threw their weight behind conservative candidates and Tea Party favorites in the midterm elections, often bucking the party establishment in doing so. Notably, they both backed Christine O'Donnell in the Delaware's Republican Senate primary election, despite her longshot chance of winning the general election; DeMint even suggested he'd rather see O'Donnell lose than see moderate Republican Mike Castle--who polls indicated would win the general election--become Delaware's next Senator.

DeMint has also gone rogue from the Republican leadership on a several recent issues, pushing to ban earmarks despite Senate Minority Leader Mitch McConnell's opposition to the idea, and criticizing the tax cut compromise Republicans brokered with President Obama.
