PORTLAND, Maine, July 9 (Reuters) – Graham Platner will formally exit the Maine Senate race Monday. He told staff in a private call Thursday. The collapse was a “slow-rolling disaster.”
Platner, 48, entered the 2026 cycle as a strong Democratic contender. Internal polls showed him trailing by 9 points last week. Donor commitments dried up. The campaign carried $2.1 million in debt.
The implosion began with a single event. A leaked memo from May detailed disorganization within the field operation. Key staffers resigned in June. “Morris Katz: I’m deeply disappointed,” said the state party chair in a statement.
Katz had endorsed Platner in March. He withdrew that endorsement Wednesday. The race now favors incumbent Republican Susan Collins, who leads by 12 points in the latest Portland Press Herald poll.
Platner’s exit deadline is Monday. He will not file for an extension. His campaign manager, Anne Liu, confirmed the timeline to Axios. The Axios report broke the news.
The “slow-rolling disaster” term originated from a senior advisor. It described the gradual erosion of staff morale. Fundraising fell 40% month-over-month since April. The campaign spent $0 on advertising in the final two weeks.
No other Democrat has filed to run. The filing deadline is August 1. Collins’ team declined to comment.
