Graham Platner spent months leaning into one identity: Maine oysterman, not career politician. That blue-collar story helped him beat Governor Janet Mills in June's primary with 72% of the vote. But this week, on Monday, a serious allegation threatened to upend everything he had built.
On Polymarket's Maine Senate Election Winner, the reaction showed up almost immediately: the Democrat's share, anchored in the 60s and 70s for months, dropped sharply after the storm unleashed.
A Serious Allegation Shakes the Democratic Campaign
Politico reported Monday that Jenny Racicot, who had dated Platner on and off between 2019 and 2021, described a night that year when an intoxicated Platner came to her home uninvited and ignored her when she asked him to stop.
She later gave a similar account to CNN and said she cut off contact afterward. Platner denied it, calling the story "troubling, serious and false" and adding, "Any accusation of nonconsensual behavior is categorically false." He hasn't said whether he'll stay in the race, though he acknowledged the political cost.
Democrats Pull Back Their Support
Within hours, Democrats distanced themselves from their nominee.
Senate Minority Leader Chuck Schumer and DSCC chair Kirsten Gillibrand called the allegations "incredibly disturbing" and urged Platner to withdraw. Senator Elizabeth Warren, an earlier endorser, said stepping aside was "the best path forward." Senator Ruben Gallego and Representative Ro Khanna also rescinded their endorsements, Khanna calling the allegations "very serious and credible."
The DSCC and the Senate Majority PAC said they won't fund the race unless Platner leaves the ballot. Under Maine law, he has until July 13 to withdraw, and the party until July 27 to name a replacement: possible names include Mills, Secretary of State Shenna Bellows and former state Senator Troy Jackson.
Susan Collins Watches the Turmoil From a Distance
The five-term Republican incumbent has largely stayed out of her rival's crisis. "These allegations are appalling," Susan Collins said in a statement. "Nevertheless, it is not up to me to choose the Democratic nominee for Senate."
Collins is the only Republican senator representing a state Trump has never carried, making Maine a top Senate target this cycle: Democrats need a net gain of four seats to retake the majority in November.
Even before this week, a June 19–26 New York Times/Portland Press Herald/Siena poll of 608 likely voters had the race inside the margin of error, Platner ahead 49 to 47 percent. That survey found weak points on both sides: most voters doubted Platner's "good character," while many viewed Collins, who would turn 80 during a sixth term, as too tied to Trump and possibly too old for the job.
What the Prediction Market Is Pricing In
This week's swing on Polymarket: a sharp dip for the Democrat followed by a partial recovery suggests traders are still weighing whether the allegations end Platner's campaign outright, get absorbed by a late substitution, or fade as November approaches.
Whatever comes next, the oysterman who built a campaign on being an outsider now finds his fate tied to a decision he alone can make before July 13. Traders, like Maine Democrats, are watching the tide before deciding where to stand.
