In a post to his Twitter account announcing his decision, Northey said he hoped Rep. Steve King (R-Iowa) would jump into the race.
I have decided not to run for US #Senate. Thx for many kind, encouraging words. Hoping Congr King runs. Other good R candidates as well.— Bill Northey (@BNorthey) May 2, 2013
Northey told the Register he had made his decision "after talking with my family and thoughtful consideration."
In an interview last week with Radio Iowa, Northey said it would be difficult to walk away from a farm that has been in his family since the 1930s.
"I do have other family there that can farm it, that I could rent to,” Northey said, “but it wouldn’t be the same as me being able to get out and farm myself.”
The Republican nominee will likely face Rep. Bruce Braley (D-Iowa), who announced his intention to run in February.
