The Maine Democratic Party's state committee voted on July 8, 2026, to hold a nominating convention to select a replacement for U.S. Senate candidate Graham Platner. The decision was made during a meeting attended by over 100 state committee members, who supported the convention process. The convention will include 500 delegates elected proportionally by county committees, along with the entire state committee. Details regarding the timeline and nomination process will be announced soon, according to party officials. The meeting was closed to the press, and information was shared by an attendee with the Bangor Daily News.
Party Chair Charlie Dingman, Vice Chair Imke Schessler, and Executive Director Devon Murphy-Anderson emphasized the importance of transparency in the process. Platner is currently facing U.S. Senator Susan Collins in a significant race, but has been under scrutiny following allegations made against him in a report by Politico. The Maine Democratic Party, along with the national party, has distanced itself from Platner and called for his withdrawal from the race. This convention marks a notable event as it is the first time Maine Democrats have used such a large-scale convention to replace a statewide nominee.
The vote occurred amidst tensions between Platner and the state party, with accusations of him attempting to influence the nomination process. Platner's campaign has denied these allegations. Rep. Valli Geiger, a potential replacement candidate, is reportedly working to facilitate a resolution that would lead to Platner stepping down from the race.
