Maine Democrats Meet to Choose New Senate Nominee in High-Stakes Race Against Susan Collins
By Kerry Mitchell | SCN NEWS
Maine Democrats are gathering in Bangor to select a new U.S. Senate nominee who will challenge longtime Republican Senator Susan Collins in one of the most closely watched races of the 2026 midterm elections—a contest that could influence control of the U.S. Senate.
The special nominating convention was called after Democratic nominee Graham Platner withdrew from the race following allegations of sexual assault made by a former girlfriend. Platner has denied the allegation but stepped aside after losing support from key Democratic leaders and allies. Under Maine law, the state Democratic Party is authorized to choose a replacement nominee before the election deadline.
More Than 600 Delegates Vote
More than 600 elected Democratic delegates are participating in the convention, where they will vote to choose the party's new Senate candidate.
The replacement process is unprecedented for the Maine Democratic Party and comes under tight legal deadlines, with the party required to submit its nominee before the November general election ballot is finalized.
Troy Jackson Emerges as Front-Runner
Former Maine Senate President Troy Jackson has emerged as the overwhelming favorite to secure the Democratic nomination.
Jackson, a fifth-generation logger and longtime labor advocate from northern Maine, entered the race after Platner's withdrawal and quickly secured support from hundreds of delegates. He has also received backing from progressive organizations and figures aligned with Senator Bernie Sanders.
His remaining challenger is biopharmaceutical executive Saundra Pelletier, though political observers expect Jackson to prevail at the convention.
Susan Collins Faces Another Tough Race
Republican Senator Susan Collins, who is seeking a sixth term, remains one of the GOP's most prominent moderate voices in the Senate.
Collins enters the campaign with a significant fundraising advantage and decades of statewide political experience. However, Democrats believe Maine remains one of their best opportunities to flip a Republican-held Senate seat as they seek to regain control of the chamber.
Why This Election Matters
Republicans currently hold a narrow majority in the Senate, making every competitive race critical.
Political analysts consider Maine one of the key battlegrounds that could determine which party controls the Senate after the November elections. Both national parties are expected to invest heavily in advertising, campaign operations and voter outreach once the Democratic nominee is confirmed.
Most Unique Fact
Rather than holding another statewide primary, Maine Democrats are using a special convention of more than 600 elected delegates to choose their replacement nominee—an unusual process triggered after their original candidate withdrew from the race.
