Graham Platner, the Democrat challenging Republican Sen. Susan Collins in Maine, is facing a major problem just months before the November election. A woman said she was his girlfriend in 2021, and she told reporters that Platner entered her home while drunk and forced her to have sex against her will. Politico broke the story on July 6, 2026, and NPR reported it the same day, noting the network had not verified her claim.

Platner denies the claim completely. "Any accusation of non-consensual behavior is categorically untrue," he said. He called the allegations "troubling, serious, and false." His campaign team went further, saying the accusations were "coached and coordinated by out of state establishment operatives" — meaning they claim opponents orchestrated the allegation. In a social media video, Platner said the campaign was "taking the time to reflect on the best path forward." This language suggested his team was unsure whether he should stay in the race.

Problems Keep Piling Up

This allegation is the newest problem for Platner. Other controversies have followed him since before he won the Democratic primary in June 2026.

In June, the Wall Street Journal reported that Platner had sent sexually explicit text messages to several women around the time he married his wife, Amy Gertner. The New York Times published a related story that included accounts from three women who had dated Platner. They said his behavior was "unsettling" and sometimes physically threatening. Those same reports mentioned an allegation that Platner has a Nazi symbol tattoo, which angered Democratic leaders, Politico reported.

The problems started even before the primary. In October 2025, Platner fired some staff and hired a new campaign manager. He also required people working for him to sign agreements saying they would not talk publicly about the campaign — a common practice when an organization is dealing with scandals, Politico reported. That same month, Platner said offensive social media posts from his past were linked to his military service.

Still, Platner won his party's primary anyway. Senate Democratic leader Chuck Schumer met with him in June, Reuters reported, showing national Democrats were still backing him. Rep. Ro Khanna defended his support in June too, saying Platner had "a dark chapter in his life" but not withdrawing his endorsement, Politico reported.

Why This Matters Beyond Maine

This race is important for Democrats across the country. Democrats need to win four more Senate seats than Republicans to control the chamber, and Maine is one of their best chances. Platner is an oyster farmer and former Marine, and Maine voters have a history of voting for different parties in different races — they might be willing to vote for a Democrat while voting Republican for president.

Sen. Collins has survived as a Republican in a state that leans Democratic by building a reputation as independent and willing to break with her party sometimes. Democrats thought Platner could take away some of her voters. That plan now has a major obstacle.

A candidate facing a serious sexual assault allegation that he denies but cannot fully disprove before November, and whose campaign is questioning whether to keep going, is not the candidate Democrats were counting on. What Platner does next — whether he stays in or drops out — will reshape Democrats' chances of gaining Senate seats.
