Recent polling averages show Democrat Troy Jackson maintaining a narrow but consistent lead over five-term Republican incumbent Susan Collins in the days before the November 3 election, with late surveys from NYT/Siena, YouGov, and others placing Jackson ahead by 4–6 points among likely voters. This positioning has shaped trader consensus reflected in current market pricing. Key drivers include stronger independent and unenrolled voter support for Jackson, reduced crossover backing for Collins, and national headwinds affecting Republican candidates. Maine’s ranked-choice voting rules and high early voting participation add procedural layers, while closing campaign messages have focused on economic concerns and Senate control stakes. No major late-breaking events have altered the final-week trajectory.
