Montana

As of Jul 1, 2026

Cook Political Report moved Montana's open Senate seat to Toss-Up, a striking reclassification for a state Donald Trump carried by 17 points in 2024. Inside Elections followed suit, while Sabato's Crystal Ball holds at Likely R. The catalyst was the late withdrawal of incumbent Steve Daines at the filing deadline, converting what looked like a safe Republican hold into genuinely contested terrain. The Republican field now consolidates around Kurt Alme, the former U.S. Attorney for Montana, heading into a June primary. On the Democratic side, Reilly Neill leads a thin field. The variable that scrambled every early projection is Seth Bodnar, the former University of Montana president, running as an independent and still collecting petition signatures. A credible independent candidacy in a state with a strong tradition of ticket-splitting (Jon Tester held this Senate seat for eighteen years as a Democrat) is exactly the kind of disruption that strains partisan modeling. Montana's economy is bound to extractive industries and agricultural commodity markets, sectors where federal regulatory posture shapes livelihoods more directly than in most states. The state's independent-voter population has historically demanded candidates who can argue across that divide rather than simply absorbing national party messaging. As of the most recent available polling, Republicans hold a 19-point lead, but that figure predates Bodnar's potential ballot-qualification and was gathered before the full implications of the open-seat dynamic settled in. Whether the seat stays Republican or becomes the cycle's marquee upset depends less on party machinery than on whether Bodnar qualifies and how Alme performs in a primary electorate shaped by Daines's abrupt exit.
