Troy Jackson, a state senator from Allagash, has become the Democratic nominee for Maine's U.S. Senate seat in 2026, setting up a challenge to Republican incumbent Susan Collins. The move comes as polls and prediction models show Democrats with a 66.5% chance of flipping the seat.
The Nominee's Path
Jackson, who previously served as the Maine Senate president, stepped into the race after the previous Democratic candidate withdrew. The state party quickly rallied behind him, avoiding a contested primary. Jackson's campaign has already begun highlighting his rural roots and legislative record on labor and environmental issues.
What the Numbers Say
A widely cited prediction model gives Democrats a commanding edge in the 2026 race. The 66.5% probability reflects Collins's narrow path to reelection in a state that has trended Democratic in recent presidential cycles. Collins last won in 2020 by a margin of 8.6 points, but her approval ratings have dipped since her vote to confirm Justice Brett Kavanaugh.
The Stakes in Maine
Collins has been a key moderate vote in the Senate, often breaking with her party on abortion and infrastructure. Her ability to cross party lines has helped her survive in a state that has voted for Democrats in every presidential election since 1992. But the 2024 election will test whether that formula still holds.
Jackson's campaign is expected to focus on health care costs, prescription drug pricing, and the rising cost of living. He has already accused Collins of being too close to pharmaceutical lobbyists.
The 2026 race is now formally set. Both campaigns are gearing up for what is likely to be one of the most expensive Senate contests in the country. Whether national Democratic money flows heavily into Maine, or the party's attention is split among other targets, will shape the final outcome.
