Republican Aaron Flint holds a strong lead in the MT-01 House race due to the district’s Republican lean (R+5 PVI) and the open-seat dynamic following incumbent Ryan Zinke’s retirement. Flint secured the GOP nomination with President Trump’s endorsement and has emphasized his Army veteran background and radio-host name recognition. Recent campaign attacks have focused on Democrat Sam Forstag’s prior lobbying work for groups including the ACLU and Planned Parenthood, including support for local sales and property tax measures. These efforts coincide with Democratic odds declining sharply in prediction markets over the past week. Polling averages remain tight near even, yet trader consensus reflects the structural advantages and negative messaging momentum favoring the Republican nominee ahead of the November 3 general election.
