From there, a June 3 primary in Mississippi is the next marquee showdown. State Sen. Chris McDaniel (R) has the backing of the Club and the Senate Conservatives Fund in his bid to unseat Sen. Thad Cochran (R). But unlike the senators who were felled during the past two cycles in primaries, Cochran and his allies hit the ground running against McDaniel. A super PAC supporting Cochran has been bludgeoning McDaniel on the air. Questions about controversial statements McDaniel made in the past have set the challenger back, too. But since he has the backing of powerful outside groups, McDaniel should not be counted out.
