Maine state Representative Valli Geiger, a Democrat from Rockland, has come to national attention as a potential replacement for Senate nominee Graham Platner, who is facing allegations of sexual assault. Geiger confirmed that Platner contacted her Monday night, praising her as a "fighter" and asking if he could put her name forward for the ballot.

Platner's campaign has stated that he has not yet made an endorsement decision but confirmed he did encourage Geiger to consider running if he were to step aside. Geiger, who had previously expressed support for Platner and credited him with helping secure funding for rape-kit tracking in Maine, posted Tuesday that she would not "throw Graham under the bus." She also stated she would not "slander or accuse" Jenny Racicot, the woman who accused Platner of rape, "of anything more than telling the truth as she experienced it."

Geiger is a third-term state representative, serving on the Labor Committee and the Energy, Utilities and Technology Committee. Her legislative biography highlights her background as a former nurse and health policy analyst, holding a master's degree in sustainable design. Prior to her state legislature service, she spent six years on the Rockland City Council, including one year as mayor.

Platner has denied the sexual assault allegation. The potential for a ballot replacement has also brought other names into consideration. According to Maine law, if Platner formally withdraws by 5 p.m. on July 13, the Maine Democratic Party can select a new nominee through its internal process, with a replacement required by July 27. Other Democrats who have been mentioned as possible successors include former gubernatorial candidate Troy Jackson, Secretary of State Shenna Bellows, and former Maine CDC Director Nirav Shah.
