Recent polling averages show Democrat Troy Jackson holding a narrow lead or statistical tie with Republican incumbent Susan Collins in Maine’s U.S. Senate race, with surveys from late September and early October placing Jackson at 49-51 percent and Collins at 46-48 percent among likely voters. Jackson’s nomination in July after the prior Democratic candidate’s withdrawal has allowed focus on working-class credentials and priorities such as abortion access, healthcare, and cost of living, where voters give him edges in recent surveys. Collins, seeking a sixth term and chair of the Senate Appropriations Committee, emphasizes her record securing federal funding for the state and cross-aisle work, areas where she maintains advantages. A closely contested contest with roughly one month until Election Day has produced trader consensus reflecting these tight fundamentals and limited undecided voters.
