CHEYENNE, Wyo. (AP) — Democratic Albany County Commissioner Tim Chesnut says he will run for the U.S. Senate.

The 47-year-old Laramie resident admitted his chances of victory were small. But Chesnut hopes his campaign will help shift the political climate away from the hyperpartisanship seen today and encourage politicians to find middle ground.

Chesnut will face perennial office-seeker Al Hamburg, a retired painter from Torrington, in the August Democratic U.S. Senate primary.

Incumbent Republican U.S. Sen. John Barrasso is being challenged in the Republican primary by former soldier of fortune Thomas Bleming of Lusk.

Chesnut tells the Associated Press  that if elected he would work to move past entrenched party lines on either side and try to find solutions to the nation's problems.
