What happened
Republican Senator Susan Collins has lost her bid for a sixth term in Maine, conceding defeat to Democrat Troy Jackson in one of the most closely watched races of the 2026 midterm elections. Collins called Jackson to concede on Tuesday night, a step confirmed by Jackson’s campaign to USA Today, after CNN and Fox News projected Jackson as the winner. Reuters also reported the concession on Tuesday, describing the result as a major pickup for Democrats.
Collins had served in the Senate since her first election in 1996, building a reputation as one of the chamber’s most prominent moderates and, since January 2025, as chair of the powerful Senate Appropriations Committee. She was the only Republican senator seeking re-election in 2026 in a state that voted for Democrat Kamala Harris in the 2024 presidential election, and her race had become central to Democratic hopes of winning back the Senate.
Jackson, 58, took an unusual path to the nomination. He first ran for governor, finishing third in a crowded Democratic primary in June 2026. When Graham Platner, the original Democratic Senate nominee, dropped out in July after facing allegations he denied, Democrats selected Jackson through a nominating convention. Jackson campaigned on his blue-collar roots as a fifth-generation logger from the remote town of Allagash, on universal healthcare and other populist policies, and drew support from high-profile progressives including Vermont Senator Bernie Sanders.
Reuters reported that economic pressures shaped the race in Maine, a largely rural state known for harsh winters. The Iran war pushed up fuel and home heating oil prices, while trade tensions with Canada weighed on tourism, lobstering, logging and other pillars of the state’s economy. Those headwinds, Reuters said, helped Jackson overcome his late entry into the race. Final pre-election polls had pointed the same way: a New York Times/Portland Press Herald/Siena poll showed Jackson leading 51% to 45%, and a University of New Hampshire survey put him ahead 54% to 45%.
The Maine result was part of a wider Democratic night. Democrats flipped Senate seats in Texas, South Carolina, Kansas, Ohio and Iowa as well as Maine, and were projected to take the Senate majority, as covered here: https://worldpulsewire.com/2026/11/04/democrats-take-full-control-of-congress/ In Georgia, Democrat Jon Ossoff was projected to win re-election, a result covered here: https://worldpulsewire.com/2026/11/04/ossoff-projected-to-win-georgia-senate-race-as-democrats-take-early-midterm-wins/
Why it matters
Collins’s defeat removes one of the Senate’s longest-serving and most independent-minded Republicans, and it closes a chapter in Maine politics that lasted three decades. For thirty years, Maine voters repeatedly returned Collins to Washington even as the state moved toward Democrats in presidential elections, a record that made her one of the party’s most durable statewide candidates. Her loss shows that even that personal brand could not survive the political mood of 2026.
The seat also matters for the balance of power. Maine’s flip was one of the pickups that carried Democrats to a Senate majority, giving the party control of the chamber that confirms judges and senior administration officials. Losing the Appropriations chairmanship as well means Republicans lose a senior figure in the negotiations over government spending, an area where Collins had long played a central role.
For Democrats, Jackson’s win is a symbolic prize as well as a practical one. Democrats had not won a Senate election in Maine since George Mitchell in 1988, according to election records cited in coverage of the race. Breaking that run in a state where their nominee entered the contest only months before election day underlines how far the political ground shifted on 3 November.
For Republicans, the result is a warning about the limits of incumbency. Collins outperformed polls in past elections, and her team hoped she could do so again. This time the polling lead held, and the party lost a seat it had held since 1997, along with the institutional knowledge of a senator who had served through six presidential administrations.
What happens next
Jackson will take his seat when the new Congress convenes in January 2027, subject to certification of the Maine result. Collins has promised a smooth transition, telling Jackson in her concession call that she and her staff would work to ensure an orderly handover. The formal count in Maine will continue and be certified in the coming weeks, but the concession and the projections leave little doubt about the outcome.
In Washington, Jackson will join a Democratic Senate majority that must now choose its leaders, assign committee posts and set its first legislative priorities. His background as a former Maine Senate president and as a logger from Aroostook County gives him a distinctive profile in a chamber where few members come from manual trades, and his campaign promises on healthcare and working people’s living costs will be watched closely in his first months.
Collins’s departure also opens a question about the future of the Senate’s moderate bloc. She was often a decisive vote in close contests, and her absence changes the arithmetic of bipartisan deal-making. Whether her successor in the Republican Party, or the Senate as a whole, fills that role will shape how the new Democratic majority governs.
