Republicans keep Montana legislative majority despite blue wave

Montana’s Red Map Holds Firm as Blue Wave Swells Nation

Across the nation, voters reshaped state legislatures last Tuesday, but in Montana, the political tide crept in only modestly. Despite a significant “blue wave” that gave Democrats control of legislative chambers in eight other states, including Arizona, Texas, and Michigan, the Treasure State’s Republican majority remains firmly intact. Democrats picked up two seats in the state Senate and at least one in the House, according to the Montana Free Press, a clear sign of momentum but not the breakthrough some had anticipated.

Why the disconnect? The 2023 redistricting maps, which Montana Free Press reported were favored by Democrats at the time, have created a political situation that is both less competitive and more resistant to sudden swings. The map, by reducing the number of closely contested districts, effectively walled off Republican-held strongholds, insulating them from the kind of losses seen elsewhere.

A Tale of Two Maps

In 2023, Democrats supported a redistricting plan that, by concentrating Democratic voters in fewer districts, made it nearly impossible for Republicans to maintain their supermajority status. The plan worked. It helped Democrats claw back 10 House seats and two Senate seats in 2024, ending their status as a “bicameral superminority”—the first time that had happened in Montana’s modern history.

But as the 2026 blue wave hit, that defensive strategy came back to haunt them. The very logic that made districts safer for Democrats also made it harder for them to find new places to grow. While other state Democratic parties were winning big, Montana’s gains remained metered.

“By creating relatively few competitive districts, the map insulated Republicans from significant losses even in a strong Democratic year,” Sen. Greg Hertz, R-Polson, who chairs the Montana Republican Legislative Campaign Committee, told Montana Free Press in a text message. His analysis was echoed by Yahoo News, which reported that Montana Republicans “outperformed their counterparts in many other states.” The map, in essence, performed exactly as it was designed to: it preserved Republican majorities.

Democrats, however, frame the results differently. Ciara Maxwell, director of the Montana Democratic Legislative Campaign Committee, defended the 2023 maps as “very fair” and attributed the party’s gains to the strength of its candidates. “Democrats have shown that we are increasingly competitive every cycle,” Maxwell told Montana Free Press.

Picking up a couple seats in the Montana Legislature is not nothing. I think it’s very good.

The Fight on the Ground, Vote by Vote

The most dramatic contests unfolded in Cascade County, around Great Falls, an area where Democrats have been methodically chipping away at Republican dominance since 2022, when the party lost every legislative race there. This year, they flipped one seat outright and came within a hair’s breadth of flipping two more.

In Senate District 10, which includes downtown Great Falls, Democrat Margaret Mitchell defeated Republican Jessica Dyrdahl to capture an open seat. The race was left vacant after incumbent Jeremy Trebas opted to run for the Public Service Commission. Mitchell, who spoke with Montana Free Press on Thursday morning, found encouragement in the narrow margins. “Even in some of the areas that were very heavily red, we made inroads,” she said.

Meanwhile, two House races in Great Falls were nail-biters. With 97% of the votes counted, Democrat Steve Keller led incumbent Melissa Nikolakakos, R-Great Falls, by a razor-thin 46 votes in House District 20. In another House race, Republican Rep. George Nikolakakos defeated Democrat Mindy Leach by only four percentage points.

Democrats also found success in other parts of the state. They flipped Senate District 29, which encompasses Livingston, Clyde Park, and part of Bozeman, where Rep. Scott Rosenzweig, D-Bozeman, defeated Republican Jason Gunderson. The seat was open due to the retirement of Sen. John Esp, R-Big Timber. In a testament to the map’s competitiveness, incumbent Sen. Mary Ann Dunwell, D-Helena, held on to her seat in Senate District 42 by just 130 votes against Republican Stephen LaPraim.

The Math of a Minority

Even if Democrats lose the two uncalled House races in Great Falls and Billings, their minority will grow to 20 in the Senate and 43 in the House, up from 18 and 42. That’s a meaningful shift, but it falls short of challenging Republican control.

Republican leadership insists the change is purely cosmetic. “The overall makeup of the Legislature — among partisanship and among legislative factions — is functionally unchanged from what it was before the election,” Kyle Schmauch, chief of staff and communications director for the Republican Senate majority, told Montana Free Press.

House Minority Leader Rep. Katie Sullivan, D-Missoula, who was termed out of the House and chose not to run for the Senate, offered a more optimistic take for her party. “Picking up a couple seats in the Montana Legislature is not nothing,” Sullivan said. “I think it’s very good.” Her perspective suggests that for a party clawing its way back from historic lows, even incremental gains represent a crucial step forward.

The open question now is how this slightly larger Democratic minority will interact with a Republican majority that feels secure. As political reporter Mike Dennison told Yahoo News, Montana still has a bloc of moderate Republicans. The increased Democratic presence could potentially give those moderate Republicans the partners they need to drive certain issues, even influencing leadership choices, something that could subtly alter the dynamics of the 2027 legislative session.

Both parties will head to Helena for orientation next week to elect their leadership. The real work, however, begins in January. The story of Montana’s 2026 election is not one of a dramatic upset, but of a state where the political map has become a more powerful predictor of outcomes than the national mood.
