Wisconsin GOP Primary Pits Establishment vs. Insurgents

Primaries are being held in Connecticut, Minnesota and Florida Tuesday.

But many eyes are on a Republican Senate primary in Wisconsin, where former governor Tommy Thompson's huge lead in the polls has slipped to a dead heat and, despite being one of the state's most popular politicians, he's now in the race of his life.

Last week the 70-year-old Thompson felt compelled to prove his physical fitness by dropping to the floor at the Milwaukee Journal Sentinel while on a visit and doing fifty push-ups in one minute. (Video here.)

His opponents include 48-year-old hedge fund manager and political newcomer Eric Hovde, former congressman and Tea Party favorite Mark Neumann and former speaker of the state assembly Jeff Fitzgerald. The winner faces Democrat Tammy Baldwin.
