Maine Democrats race to replace embattled Senate nominee Graham Platner

Maine Democrats raced to line up a replacement for Graham Platner after a new sexual assault allegation intensified pressure on their embattled Senate nominee. Platner won the Democratic primary on June 9, but party leaders publicly called on him to withdraw as the race for Susan Collins’s seat took on added urgency in a contest that could help decide control of the U.S. Senate.

The timing leaves Democrats with almost no room to maneuver. Under Maine election law, Platner would have to withdraw by July 13, 2026, for the party to replace him on the general-election ballot. The Maine Commission on Governmental Ethics and Election Practices says Democrats would then have until July 27, 2026, to make a replacement nomination. If that happens, Maine Secretary of State officials can produce new ballots or amend ballots already printed. If Platner drops out after the withdrawal deadline, the vacancy cannot be filled on the ballot.

That narrow window has already set off an internal scramble. Progressives and moderates are weighing competing options for who should take Platner’s place, a fight that could shape not just the Maine race but the party’s broader posture heading into a high-stakes Senate battle. Former Maine Senate President Troy Jackson has filed paperwork to explore a run, while Nirav Shah, Maine’s former public health director and now a gubernatorial candidate, has also been floated as a possible alternative.

The compressed calendar means any replacement would have to build a statewide Senate campaign in days, not weeks. That matters in a state where Democrats had hoped Platner could challenge Collins, who is seeking a sixth term. Instead, the party is now trying to decide whether to salvage the race with a quick pivot or stand behind a nominee whose campaign has become mired in scandal.

Platner has denied the allegations and said he is “taking the time to reflect” on his next steps. His supporters have been shaken by the latest claim, while national Democrats are weighing the political damage against the risk of losing a seat that could help determine which party controls the Senate.
