Rep. Steve King (R-Iowa) late Friday announced on Twitter that he would not run for Senate in 2014.
King becomes the third prominent Republican in the past two weeks to opt against a run.
On Thursday, Iowa Agriculture Secretary Bill Northey (R) tweeted that he would not seek the Republican nomination for the seat now held by retiring Sen. Tom Harkin (D-Iowa).
Northey said he hoped Rep. Steve King (R-Iowa) would jump into the race.
Iowa Lt. Gov. Kim Reynolds (R) announced last week that she would not seek the seat.
In April, King said he saw a "path to victory" if he ran and was "close" to making a decision.
However, King said his polling showed any Republican faces an "uphill climb" to victory, — a hint he might not have been totally sold on a bid.
