SUMMARY
- Steve Daines will not seek reelection after more than a decade in Congress
- His exit makes him the sixth GOP senator stepping aside this cycle
- The open Montana seat reshapes the 2026 Senate map in a closely divided chamber
WASHINGTON — Steve Daines announced Wednesday that he will not seek reelection this fall, creating an open Senate contest in Montana and adding to a growing list of Republican retirements ahead of the midterm elections.
Daines’ decision immediately transforms Montana into one of the most closely watched Senate battlegrounds.
In a statement, he said serving in the US House and Senate for thirteen years was the greatest honor of his professional career and that he had wrestled with the decision for months before opting not to run again.
First elected to the Senate in 2014, Daines defeated then-Gov. Steve Bullock in 2020. He chaired the National Republican Senatorial Committee from 2023 to 2025, overseeing GOP campaign strategy during a volatile election period.
His retirement follows similar announcements from Sens. Thom Tillis, Tommy Tuberville, Joni Ernst, Cynthia Lummis and Mitch McConnell, all of whom have opted against reelection this cycle.
Daines endorsed Kurt Alme, US attorney for the District of Montana, who filed shortly before Tuesday’s deadline. President Donald Trump also endorsed Alme, calling him exceptional in a social media post.
David Parker, professor of political science at Montana State University, said open seat races in smaller states often attract significant outside spending because “there is no incumbent advantage to anchor voter preferences.”
Jessica Taylor, Senate analyst at the Cook Political Report, said Montana’s Republican lean gives the GOP an initial edge but that retirements can introduce unpredictability in candidate quality and turnout dynamics.
Sen. Tim Sheehy said Daines was stepping aside “at the height of his power to clear the way for a new generation.”
Former University of Montana President Seth Bodnar, who filed as an independent, said Montanans deserve an independent voice focused on lowering costs and protecting state values.
Candidate filing deadlines have passed, and party committees are expected to ramp up fundraising and advertising in the coming months as the Montana Senate race gains national attention.
Daines’ retirement marks a significant shift in Montana politics and contributes to broader turnover within the Senate GOP conference, setting the stage for a competitive open seat campaign with national implications.
