TOP G.O.P. DONORS SEEK GREATER SAY IN SENATE RACES
-NY Times, 02/03/13
Normal Repub pols have had just about enough of the neocon/teabagger influence in losing major elections, including the WH, cycle after cycle and are gearing up to oust extreme Repub pols - Iowa's Congressman Steve King (R) will be their first target...King has designs on the Senate seat Tom Harkin (D) will vacate in 2014 but a group formed by Karl Rove of American Crossroads fame, The Conservative Victory Project, intends to counter extreme Repub pols that have ousted normal Repub candidates and they plan to recruit seasoned reasonable Repub candidates.
It's interesting to watch the GOP eat it's own...in 2010 the GOP could not cater enough to the neocons/teabaggers - now they're reaping what they sowed.
