U.S. Senator Jon Tester says he's looking forward to running for his senate seat again, as opposed to running against Denny Rehberg or any other republican. Tester says there's a difference between running for the seat and running against someone for it.

Rehberg announced earlier this month that he would challenge tester for the senate in 2012. Tester says he believes his work in Congress will stand up for itself.

Tester says he's worked for Montana farmers and ranchers, businesses and veterans. Just as Rehberg said he would continue his work in the House, Tester says his main focus for now is his work in the Senate.
