HELENA, Mont. -

Democrats John Driscoll and John Lewis have both spent much of their lives in politics, yet their paths to the June House primary couldn't be more different.
    
The 67-year-old Driscoll is a former public service commissioner and state House Speaker. He's not taking donations in the primary and hopes to sway voters through personal connections built over a political career that dates to the early 1970s.
    
The 36-year-old Lewis spent 11 years working for former U.S. Sen. Max Baucus before launching his first bid for elected office last fall. He's had strong backing from the Democratic establishment and raised almost $700,000.
    
Absentee ballots will be mailed to voters May 5. The primary is on June 3.
    
Five Republicans are vying for their party's nomination.
