Recent polling averages show Democrat Troy Jackson holding a narrow lead of roughly 2–3 points over Republican incumbent Susan Collins among likely voters in the final weeks before the November 3 election, with several late-October surveys indicating a Jackson advantage of 4 points or more. This positioning reflects elevated Democratic enthusiasm, stronger early voting trends for Jackson, and voter concerns over Collins’s alignment with the current administration on key issues, which have narrowed her traditional crossover appeal in the state. Markets assign Jackson a higher probability than most forecasters because traders weigh these late shifts and the race’s nationalization more heavily than Collins’s historical polling resilience and appropriations influence. Ranked-choice voting adds a layer of uncertainty in a close contest.
