Incumbent:Open seat

Steve Daines stunned Montana by withdrawing minutes before the March filing deadline and endorsing U.S. Attorney Kurt Alme, a maneuver both parties called a coronation. The fallout created a genuine three-way race: Alme for the GOP, Democrat Alani Bankhead, and independent former University of Montana president Seth Bodnar. Markets keep Republicans near 80 percent, but the independent lane makes Montana the cycle's most interesting tail-risk trade.
