An AP-projected upset in Maine ending Susan Collins' long Senate tenure, with candidate background and policy consequences.
Five-term incumbent loses in Maine
Democrat Troy Jackson defeated Republican U.S. Senator Susan Collins in Maine's November 2026 election, according to the Associated Press. Collins, who had served for about 30 years and sought a sixth term, conceded the race. Jackson is a former president of Maine's state Senate who worked in logging before entering politics. The outcome flips a Republican-held seat, helping Democrats take control of the U.S. Senate.
A compressed campaign season
Jackson entered the contest after the original Democratic nominee withdrew, leaving a compressed campaign in a state where Collins had previously prevailed in difficult elections. Jackson emphasized wages, health care, housing and the cost of living. Collins campaigned on her experience, institutional seniority and willingness to differ from President Donald Trump at times. Voters evaluated those contrasting records amid national dissatisfaction with prices and the country's direction.
Why the seat was important
Maine's Senate race was a leading Democratic pickup opportunity from the outset, as it was one of the few Republican-held seats in a state that voted for the Democratic presidential ticket in 2024. Collins' defeat affects Senate committee leadership and the partisan distribution of votes when the next Congress convenes. The Associated Press also reported Democratic pickups across several more Republican-held states.
The next stage
Jackson is projected to enter the Senate in January 2027. As with other U.S. races, formal state certification follows news projections. Canadians looking for broader consequences should watch subsequent bills, hearings and administration responses rather than assuming this one result changes trade rules automatically. The article records the called race as of November 4.
