Four Democrats Make Their Case in Montana’s Western Congressional District Primary
Why It Matters
Montana’s First Congressional District — covering western Montana and anchored by Democratic-leaning cities including Missoula, Bozeman, and Butte — has emerged as one of the more closely watched House races of the 2026 midterm cycle. With incumbent Republican Ryan Zinke announcing he will not seek re-election, the seat has opened in a way that gives the eventual Democratic nominee a realistic, if still uphill, shot at flipping it.
The outcome of the Democratic primary will determine whether the party can field a candidate capable of peeling away independent and Republican voters in the surrounding conservative counties — a requirement analysts say is non-negotiable for a November win.
What Happened
Four Democratic candidates are competing in the MT-01 primary, each making a distinct argument about who is best positioned to win the general election. The candidates — Ryan Busse, Sam Forstag, Russ Cleveland, and Matt Rains — have participated in a series of campaign events and candidate forums this spring, drawing out both ideological similarities and sharp personal contrasts.
Zinke’s March announcement that he would not seek re-election removed the incumbency advantage from the Republican field and triggered what observers describe as a competitive GOP primary of its own. Election analysts still rate the district as a likely Republican hold, but the open seat and the broader midterm environment have raised Democratic hopes.
At an April candidate forum in Helena, intraparty tensions surfaced openly. Busse and Cleveland both targeted Forstag — Busse over what he characterized as a campaign website feature that could invite outside group spending, and Cleveland over Forstag’s endorsement by the state AFL-CIO, which Cleveland suggested could compromise Forstag’s stated opposition to data centers. Forstag denied accepting dark money or corporate PAC contributions, and countered by highlighting his working-class background in contrast to the personal wealth of other candidates.
Rains, the most moderate candidate in the field, has taken a different approach — arguing that a Democrat running in MT-01 needs all available financial support, corporate or otherwise, to be competitive in November.
By the Numbers
4 — Democratic candidates currently seeking the MT-01 nomination: Ryan Busse, Sam Forstag, Russ Cleveland, and Matt Rains.
3 — Consecutive presidential elections in which Montana voters have backed Donald Trump, underscoring the district’s overall Republican lean despite Democratic pockets in its major cities.
12+ — Historically conservative counties surrounding the district’s Democratic strongholds where the eventual nominee will need to make inroads.
2024 — The last election cycle in which former Sen. Jon Tester, running unsuccessfully for re-election, nonetheless carried MT-01, demonstrating that western Montana voters are willing to support Democratic candidates at the federal level.
Zoom Out
Montana’s western district race reflects a broader national pattern heading into the 2026 midterms, in which open Republican-held seats — particularly those vacated by incumbents — are drawing increased Democratic attention and resources. Nationally, the political environment surrounding Congress remains fluid, with analysts weighing whether dissatisfaction with federal governance translates into actual seat changes in districts that have trended Republican.
The intraparty debate playing out in MT-01 also mirrors tensions within the Democratic Party at large: whether to run candidates who align closely with national progressive priorities or to field more moderate, regionally rooted candidates who distance themselves from a national brand that figures like former Sen. Tester have publicly described as a liability. Tester himself called the national Democratic Party “poison” and an “anvil” during his failed 2024 re-election campaign, a quote that has hung over the current primary field.
Democrats hoping for a wave election will need to navigate both domestic and foreign policy pressures that could define competitive House races across the country this cycle.
What’s Next
Primary voters in Montana’s western district will ultimately decide which of the four candidates — the firearms industry critic, the former smokejumper and union organizer, the self-described progressive independent rancher, or the agricultural moderate — carries the Democratic banner into November.
The nominee will then face the winner of what is shaping up to be a competitive Republican primary, in a district analysts still favor Republicans to hold. The general election battle is expected to turn on cost-of-living concerns, federal policy direction, and whether the Democratic candidate can make a credible case to independent and soft-Republican voters in the district’s more rural corners.
