Aaron Flint holds a strong edge in trader consensus for Montana’s open 1st District House seat because the district favored Donald Trump by double digits in 2024 and Flint secured the Republican nomination with the former president’s endorsement after incumbent Ryan Zinke retired. Flint’s recent attacks on Democrat Sam Forstag’s record as a paid lobbyist for groups including Planned Parenthood and the ACLU, plus support for local sales and property tax measures, have reinforced perceptions of vulnerability for the Democratic nominee in a Republican-leaning area. Polls remain close, with averages near a tie, but market prices reflect the structural advantage for the GOP candidate three weeks before the November 3 election.
