Montana is a weird place for politics. Not "Portland weird," but "split-ticket weird." For years, people outside the state looked at the 406 and saw a deep red stronghold, yet they couldn't explain how a guy like Jon Tester—a dirt-under-the-fingernails farmer with three missing fingers—kept winning. But the Montana Senate election landscape has shifted. Hard.
If you’re looking at the 2024 results or peering ahead to the 2026 cycle, you have to realize the "old Montana" rules are basically dead.
The Night the Blue Streak Ended
Most people thought Jon Tester was invincible. He had this "common sense" brand that allowed him to survive in a state that Donald Trump won by 20 points. He talked about his tractor more than he talked about party lines. But in November 2024, Tim Sheehy—a former Navy SEAL and aerial firefighting entrepreneur—did what no one else could. He beat Tester by roughly 7 percentage points.
It wasn't even as close as the polls suggested it might be.
The final tally saw Sheehy at 52.6% and Tester at 45.5%. Honestly, it was a gut punch for the Montana Democratic Party. Tester was the last remaining Democrat holding a statewide office. Now? The GOP holds every single one. From the Governor's mansion to the Land Board, it's a sea of red.

Why the 2024 Montana Senate Election Changed Everything
You’ve gotta understand that Montana used to love "personality" candidates. We’d vote for a Republican President and a Democratic Governor in the same breath. But the 2024 race was different. It became nationalized.
The GOP spent millions—actually, both sides spent a record-breaking torrent of cash—to tie Tester to the national Democratic platform. They hammered him on the border and inflation. Sheehy, backed by a massive endorsement from Trump, successfully framed the race as a choice between a "Washington insider" and a "new generation of leadership."
The Specifics of the Shift
- The Rural Vibe: Tester carried only six counties. He won places like Lewis & Clark (Helena) and Missoula, but the rural heartland went all-in for Sheehy.
- The Trump Effect: Trump’s presence on the top of the ticket was a weight Tester couldn't carry anymore.
- Money: This was one of the most expensive races per-voter in U.S. history. We’re talking over $100 million in total spending for a state with just over a million people.
Looking Toward the 2026 Montana Senate Election
Now that the dust has settled on Tester’s seat, the spotlight is already swinging toward 2026. This time, it’s Senator Steve Daines’ turn. Daines is the guy who basically ran the Republican effort to take back the Senate nationally (as chair of the NRSC). He’s a heavyweight.
The Montana Senate election in 2026 is already being labeled as "Solid Republican" by the Cook Political Report and Sabato's Crystal Ball. Daines has already filed for reelection and secured an early endorsement from Donald Trump.

Who is challenging Daines?
It’s a bit of a scramble on the Democratic side. Right now, we’ve got a few names in the mix:
- Alani Bankhead: An Air Force Lieutenant Colonel and leadership coach.
- Reilly Neill: A former state representative who has been active in Montana politics for a while.
- Michael Black Wolf: A tribal historic preservation officer.
There’s also talk of Seth Bodnar, the President of the University of Montana, potentially running as an independent. That would be a wild card. Independent runs in Montana are usually "spoiler" territory, but someone with Bodnar's resume could actually pull from both sides if they play it right.
What People Get Wrong About Voting Here
A lot of folks think Montana is just "South Alberta" or "North Wyoming." It’s not. We have a massive indigenous population and a growing tech sector in Bozeman that’s changing the demographics. But the "Bozeman-ification" of the state is actually driving some of the red shift. Longtime locals are frustrated by rising housing costs and they’re voting for whoever promises to "keep Montana, Montana."
Basically, the 2026 race will be a test of whether Democrats can find a new "Tester-style" moderate or if they’re going to lean into a more progressive, urban-focused platform. If they choose the latter, Daines likely walks away with a 15-point victory.

Key Dates You Need to Know
If you're a voter or just a political junkie, keep these dates on your calendar. They're coming up faster than a prairie fire.

- November 3, 2026: The General Election.
Actionable Steps for Montana Voters
If you’re living in the Treasure State, don't just sit there. Politics here is high-stakes and your vote actually carries more weight because of our low population.
- Check your registration: The Secretary of State, Christi Jacobsen, recently began using the federal SAVE tool to verify citizenship for registered voters. Make sure your status is "Active" on the My Voter Page.
- Follow the money: Keep an eye on the FEC filings. In 2024, the out-of-state "dark money" was insane. If you see a weird ad on TV, check who paid for it.
- Look at the State Senate too: While the U.S. Senate gets the headlines, 25 of the 50 seats in the Montana State Senate are also up in 2026. These are the people deciding your property taxes and school funding.
The era of the "unbeatable" Montana Democrat is over. Whether the 2026 Montana Senate election brings a new surprise or just cements the GOP's total control is up to the people who actually show up at the polls in Great Falls, Billings, and every tiny town in between.
To stay ahead of the curve, you should verify your voter registration status through the Montana Secretary of State’s portal and research the 2026 candidates' specific stances on local issues like property tax reform and public land access.
