Graham Platner’s 2026 Maine Senate Bid

Graham Platner, an oyster farmer and Marine veteran, sought the Democratic nomination to challenge Republican incumbent Susan Collins in Maine’s 2026 U.

S. Senate race. He withdrew after reports of allegations of sexual assault, which he denied, and the loss of support from prominent backers including Bernie Sanders. Maine Democrats then faced a replacement process, while progressive supporters argued that a successor should retain the campaign’s anti-establishment approach. The episode also prompted debate about candidate vetting, working-class outreach, and how Platner’s policy platform—including Medicare for All and a tax on very large unrealized fortunes—fit the party’s electoral strategy.
