Republican Aaron Flint holds a clear edge in trader consensus for Montana’s open 1st District House seat, reflecting the district’s consistent Republican tilt in recent cycles and early October campaign developments. Recent independent polling shows the race as a toss-up or slight Republican lead, with Flint at roughly 45-46 percent and Democrat Sam Forstag close behind. Flint’s campaign has intensified attacks on Forstag’s prior lobbying work for progressive organizations, including positions on taxes and immigration enforcement. Flint also held a public event supporting Border Patrol agents, underscoring enforcement priorities in a district where President Trump previously performed strongly. With voting already underway ahead of the November 3 election, these factors reinforce the market’s assessment of Flint’s advantage despite the narrow polling margin.
