For three decades, every Montanan sent to Washington to serve in the U.S. House or Senate came from the baby boomer generation. That era ended on June 2, when primary voters across the state nominated a field of candidates who collectively represent a younger and more demographically diverse slice of the electorate than the state has sent to Capitol Hill in a generation.

A Generational Shift, Both Parties

The shift is visible on both sides of the aisle. Republicans nominated three Generation X men for Montana’s two House seats and one Senate seat. Incumbent Rep. Troy Downing and U.S. Senate candidate Kurt Alme are each 59, sitting at the older edge of Gen X, while Western District nominee Aaron Flint is 46. Democrats, meanwhile, nominated candidates who skew younger still. Eastern District House nominee Brian Miller, a Helena attorney, is 54 and Gen X, but Western District House nominee Sam Forstag is just 31 — a millennial — and U.S. Senate nominee Alani Bankhead is 43.

Bankhead’s nomination carries additional historical weight: she is only the second woman the Montana Democratic Party has ever nominated for a U.S. Senate seat. The first was Dorothy Eck, who ran in 1980. Forstag, at 31, becomes one of the youngest major-party congressional nominees in recent Montana history.

The generational marker that defined the old guard — the baby boomer — was cemented in Montana politics in 1996 when Republican Rick Hill won the state’s at-large House seat, beginning a 30-year run in which every member of the delegation shared that demographic identity. Through the 2024 election cycle, that remained true. The 2025 swearing-in of Rep. Downing and Sen. Tim Sheehy, both boomers, extended the streak into its final year before this week’s primaries reshuffled the deck.

The Democratic Collapse of an Older Guard

For Montana Democrats, the generational turnover reflects something more than a natural evolution. Carroll College political scientist Jeremy Johnson noted that the party’s older statewide officeholders have steadily been eliminated — not through retirement but through defeat. “On the Democrat side, the older generation of Democrats, the statewide offices, they all lost,” Johnson said. “Once that happens, you know, that sort of eliminates that older generation of Democrats from office.”

The departure of Sen. Steve Daines, who retired after two Senate terms in 2026, removes the last prominent boomer from Montana’s delegation. Daines’s seat is now the marquee race on the November ballot, with Alme and Bankhead as the nominees.

Tester Backs an Independent

Former Sen. Jon Tester, who lost his reelection bid in 2024, has remained a presence in Montana political conversations — but not one aligned with the Democratic Party’s preferred path forward. On a recent podcast appearance, Tester said he is backing independent U.S. Senate candidate Seth Bodnar rather than the Democratic nominee. “I actually am supporting an independent candidate, a guy by the name of Seth Bodnar,” Tester said. “That’s pissed off a lot of Democrats.” Tester also declined a reported outreach from Democratic National Committee leadership about a potential party role.

A National Backdrop

Montana’s generational shift tracks a broader national trend. Baby boomers lost their majority status in both chambers of Congress in 2025. The median age in the House currently stands at 57.5 years, while the Senate median is 64.7 — figures that still reflect a substantial age premium over the general population. A 2025 Harvard Youth Poll found that only 15 percent of younger voters believed the country was heading in the right direction, a data point that has animated Democratic arguments for fielding younger candidates.

Whether fresher faces translate into electoral success in a state that has trended sharply Republican at the federal level remains to be seen. Montana last sent a Democrat to the House in the early 1990s, and the Senate seat Daines vacated has been in Republican hands since 2014. The November 3 general election will test whether the new generation of nominees on either side can move those numbers.
