Bombshell Op-Ed From Ex-Campaign Director Rocks Graham Platner on Eve of Maine Senate Primary

The Democratic primary for Maine's U.S. Senate seat was thrown into turmoil this week after Genevieve McDonald, who served as Graham Platner's campaign director from August to October 2025, published a scathing op-ed in The Washington Post on June 8 — barely a day before voters head to the polls. "Graham Platner is not someone who would be good for Maine or for the country," she wrote, in a piece that detailed a string of damaging allegations against the candidate.

McDonald, who described herself as "one of the Platner campaign's first gaslighting casualties," accused the candidate of a pattern of dishonesty and of "gaslighting" staff. Her op-ed referenced controversy over a chest tattoo with Nazi associations and what she called the campaign's "appalling" handling of it, allegations of physical misconduct involving an ex-girlfriend, and old Reddit posts in which Platner characterized rural Americans as "racist" and "stupid." She also said the campaign offered her a $15,000 severance package contingent on signing a non-disclosure agreement, which she refused.

The timing could hardly be worse for Platner, who has positioned himself as the populist outsider in the race to challenge Republican Senator Susan Collins, one of the most closely watched incumbents on the 2026 map. Maine's Democratic establishment had largely coalesced behind Governor Janet Mills, who withdrew from the contest but whose name remains on Tuesday's ballot. Consultant David Costello is also running.

Maine is one of several states holding primaries this week. Voters in Nevada and South Carolina are also casting ballots in contests that will help shape the battle for control of the Senate, where Democrats are defending a narrow path back to the majority. National strategists in both parties have watched Maine especially closely, viewing Collins's seat as one of the few genuine pickup opportunities in a cycle otherwise dominated by red-state defenses.

Platner's campaign has not yet offered a detailed public rebuttal to McDonald's specific claims, and it remains unclear how much the late-breaking allegations will move an electorate that may have already formed its impressions of the candidate. But the episode has injected fresh uncertainty into a primary that Democrats had hoped would showcase a unified front against Collins — and instead delivered an eleventh-hour airing of internal grievances on the pages of one of the nation's largest newspapers.
