Former congressman Denny Rehberg (R-Mont.), who lost to Sen. Jon Tester (D-Mont.) in 2012, is weighing a run for the House seat he forfeited to challenge Tester.

The seat is open now that freshman Rep. Steve Daines (R-Mont.), is running for the state's other Senate seat.

“People just started contacting me and asked, ‘Will you consider it?’” Rehberg told the Helena Independent Record. “I like what I’m doing, expanding a small business, but I haven’t ruled it out.”

Rehberg added that he's in no rush: "I have an opportunity to think about it. It’s not as critical for me to get started as early as they. I have my own due diligence. I’m getting around Montana a lot with my small business. I get the opportunity to talk to a lot of Montanans. I want to earn Montanans’ trust and respect and vote if I jump into this.”

Rehberg was largely viewed as a disappointing GOP Senate candidate -- particularly given he lost to Tester in a state that Republican presidential candidate Mitt Romney carried by 14 points the same day.

Democrats are aiming to make the House race competitive and have lined up behind John Lewis, a former top aide to outgoing Sen. Max Baucus (D-Mont.), who was recently nominated as the next ambassador to China. The GOP field features several current and former state lawmakers.
