Senator Steve Daines withdrew from the Montana Republican primary, vacating the seat ahead of first-quarter fundraising disclosures. Independent candidate Seth Bodnar, the former president of the University of Montana, led Q1 fundraising in what is now Montana's first open Senate race since 1976, according to Daily Montanan reporting. Daines endorsed Republican Kurt Alme, the US Attorney for Montana, on his way out of the primary.
Montana's open seat removes the incumbency advantage that has historically dominated the state's Senate calculus. Montana voted for Trump by 20 points in 2024, but Daines's withdrawal eliminates the incumbent factor that polling models built around incumbent-versus-challenger frames had priced in. Bodnar is running as an independent rather than seeking a major-party nomination; in Montana, that places him on the November ballot directly without a primary, while Republicans contest their open primary among Alme and several second-tier candidates.
A three-way contest is structurally different from a two-way one. Cook Political Report did not include Montana in its 13 April Senate rating shifts . The forecaster's models price Montana as a Republican-likely seat on the assumption that any well-funded Republican holds against any Democratic challenger. An independent leading Q1 fundraising disrupts that assumption without converting Montana into a Democratic-likely seat. Counter-view from Republican strategists: Bodnar's fundraising lead is a single-quarter snapshot, Alme has institutional advantages still to deploy, and the historical record on independent Senate candidates winning in red states is thin. Either reading makes Montana more competitive in May than it was in March.
