A coalition of conservative organizations and leaders pledged today to field primary opponents for Republican senators who “unfairly” criticize Sen. Jim DeMint, the South Carolina Republican who led an insurgent funding effort that helped elect several of the six GOP freshmen senators in the 112th Congress

DeMint has been criticized by anonymous unnamed senior Republican sources who claim his Senate Conservative Fund supported insurgent candidates who lost races to Democrats that allegedly would have been won by more moderate GOPers.
