"I really believe that politically it could be done," Northey told Radio Iowa late Tuesday afternoon. "I believe it could work for me and lots of other people."

Northey may be the GOP's best hope at contesting the open seat.

Rep. Steve King (R-Iowa) has sounded less keen on the race than he had in past weeks and many Republicans are concerned the congressman's past controversial statements could hurt his chances as the nominee, and Iowa Lieutenant Gov. Kim Reynolds (R) ruled out a bid on Tuesday.

Northey called the Senate run a "tremendous opportunity," though he said he "loves" his current job and would need to find someone to tend his farm if he does run.

"I certainly get the sense that there's support to be able to run," he said. "I think there's going to be no problem with anybody, at the end of this race, with name I.D., you know, after all the money that’s going to be spent on this."

Republicans need to win a net of six seats to retake control of the Senate. Democrats are largely on defense, with seven seats they're defending in states Mitt Romney won plus the open seat in swing-sate Iowa.
