Platner wins Maine Democratic Senate primary, vows to oust Collins

Graham Platner, a United States Army veteran and oyster farmer, has won the Maine Democratic primary for the Senate, setting up a high-stakes race against Republican Senator Susan Collins.

Platner’s victory on Tuesday came after days of questions over damaging revelations about his past personal conduct, particularly in his relationships with women.

Platner, in his acceptance speech, acknowledged voters’ concerns, pledging to earn their “trust, faith and support” over the course of the campaign.

Democrats see the race as a top opportunity to flip a Republican-held seat and a must-win as the party tries to claim control of the Senate in November.

Collins, first elected in 1996 and chair of the powerful Committee on Appropriations, is the last Republican senator from New England. Maine backed Democrat Kamala Harris over Donald Trump in the 2024 presidential race.

Platner, 41, has focused his campaign on the rising cost of living, housing affordability and healthcare, and secured early endorsements from progressive figures, including Senator Bernie Sanders. But Governor Janet Mills, who withdrew from the race citing fundraising difficulties, has yet to endorse him.

His candidacy has been clouded by a series of controversies, including reports of sexually explicit messages exchanged with women while he was married and allegations from a former girlfriend of physical intimidation.

Old online posts also surfaced in which he appeared to endorse political violence and make remarks dismissive of military sexual assault, comments he attributed to a period of acute mental health struggles, including PTSD and depression following two combat deployments.
