Troy Jackson holds a modest edge in trader pricing for the Maine Senate race due to polling averages showing him ahead by roughly 3 points among likely voters, reflecting Democratic efforts to flip the seat in a state carried by Kamala Harris in 2024. Jackson, the former state Senate president who replaced nominee Graham Platner in July after allegations against Platner, benefits from strong support among independents and certain demographics in recent surveys from UNH and UMass Lowell. Susan Collins, the five-term Republican incumbent, has countered with advantages on character and federal funding delivery in the New York Times/Siena poll, her first lead since the nomination change, amid heavy Republican advertising on taxes. The contest remains a toss-up, with mixed favorability readings and no decisive late-breaking shifts as of early October.
