The open seat in Montana’s 1st Congressional District, following incumbent Ryan Zinke’s retirement, has produced a closely contested general election between Republican Aaron Flint and Democrat Sam Forstag. Recent polling shows the candidates essentially tied, consistent with trader pricing that assigns roughly equal probability to each nominee winning while concentrating implied probability on narrow victory margins of 0–6 points for either party. Key factors sustaining the tight contest include the district’s mix of suburban and rural voters, differing policy emphases on housing, taxes, and energy, and national midterm dynamics. Upcoming campaign events and any late shifts in turnout or endorsements could widen or narrow the final margin before November 3.
