HELENA, Mont. -

Former Montana House Speaker John Driscoll is making another bid for the Democratic nomination for the state's U.S. House seat.
    
Driscoll filed his paperwork Thursday with the Secretary of State's Office.
    
Driscoll served in the Montana House from 1973-1979. He also was a member of the Montana Public Service Commission and is a retired National Guard colonel.
    
The 67-year-old Driscoll lost to former U.S. Rep. Denny Rehberg in 2008.
    
Driscoll said Friday he won't accept campaign contributions unless he wins the primary election in June. He also did not accept contributions in the 2008 race.
    
He says if elected, he intends to ask Montana Democrats to expand the party to include non-tea party Republicans and change their name to the Democratic Republican Party.
    
He faces John Lewis in the primary.
