Rep. Steve King (R, IA) apparently just announced on Twitter that he will not run for the U.S. Senate seat being vacated by Tom Harkin in 2014. Dave Weigel from Slate retweeted the message, so I'm assuming it really is King's account, not a parody.
With King, Rep. Tom Latham, Lt. gov. Kim Reynolds, and IA Ag. Secretary Bill Northey all taking themselves off the board, who will Iowa Republicans put up against Rep. Bruce Braley (D, IA)? They getting close to the third tier now-maybe state Senators or former party officials.
