Montana Lt. Gov. John Walsh announced in a new Web video that he will run for Senate in 2014, handing Democrats their first big-name recruit in the race for the open seat. Former governor Brian Schweitzer (D) surprised many by opting not to run for the seat.

Walsh’s video plays up his service in Iraq and his status as a political newcomer. He served as adjutant general of the state’s National Guard before being selected as now-Gov. Steve Bullock’s (D) running mate in the 2012 election.

Freshman Rep. Steve Daines (R) is still considering the race and is expected to run. For now, the GOP field is led by state Rep. Champ Edmunds.

The seat is considered a top pickup opportunity for the GOP following Sen. Max Baucus’s (D-Mont.) retirement.
