Montana Polling History
1988–2024
Jon Tester held the Senate for 18 years by running as an authentic Montana farmer rather than a national Democrat. He lost in 2024 when the presidential margin grew to R+20 — too large for personal brand to overcome. The last red-state Democratic Senate holdout is gone.

Analysis
The State’s Political Story
Montana was genuinely competitive in the 1990s — Clinton won in 1992 (+2.5), and Dole only won in 1996 by 2.9. The 2000 election was the shock: Bush won by 25. Montana never returned to competitiveness at the presidential level, but Tester’s Senate wins (2006, 2012, 2018) kept it on the map as a state where personal-brand Democrats could survive. His 2024 loss to Tim Sheehy ended that era. Tester ran 14 points ahead of Harris in 2024 — the largest personal premium of any candidate that cycle — but Trump’s R+20 margin was simply too large to overcome even with that exceptional performance gap.
Key Demographic Drivers
Missoula County (University of Montana) is the Democratic anchor at D+25-30. Gallatin County (Bozeman) has been rapidly transforming — from R+15 a decade ago to competitive — driven by tech in-migration, remote workers, and Montana State University growth. Lewis and Clark County (Helena, state capital) leans Democratic. Yellowstone County (Billings) is the bellwether at R+20-25. The Flathead Valley (Kalispell), eastern plains counties, and much of rural Montana run R+35-50. The Tester coalition required Missoula, Gallatin, Lewis & Clark, and strong performance in Yellowstone and native reservation counties — a fragile geographic coalition that required his personal brand to hold together.
2026 Context
No Montana Senate majority math in 2026. Steve Daines (R) won re-election in 2022; Tim Sheehy holds the seat Tester vacated through 2030. MT-1 (Ryan Zinke, R) is the only realistic Democratic target given Gallatin County’s demographic change, but Zinke has held it comfortably. MT-2 (Troy Downing) is solidly Republican. Gov. Greg Gianforte (R) is not up until 2028. Without a Tester-equivalent candidate, Democrats have no statewide viability in Montana under current conditions and are likely in a rebuilding phase through at least the 2028 cycle.
