Scott Eisen/Getty Images News
Democrat Troy Jackson defeated five-term Republican Sen. Susan Collins in Maine, flipping a Republican-held seat and adding to Democratic gains in the 2026 midterms.
Jackson, 58, a former Maine Senate president and fifth-generation logger, secured the Democratic nomination in July after Graham Platner withdrew, leaving him just over 100 days to campaign.
Collins, 73, first elected in 1996, was seeking a sixth term. She highlighted her bipartisan record and role as Senate Appropriations Committee chair, while Jackson criticized Collins’ support for President Donald Trump.
Jackson campaigned on affordability, workers’ rights, and universal healthcare, drawing support from progressives, including Sen. Bernie Sanders.
Collins had comfortably won reelection in 2020 despite Maine’s history of voting for Democratic presidential candidates. Her defeat ends nearly 30 years in the Senate.
With 72% of the expected vote reported, Jackson led Collins 53% to 47%, with 291,682 votes against 258,254, according to ABC News’ live results.
