Graham Platner, the anti-Israel progressive who took Maine’s political establishment by storm this spring, has officially prevailed in his state’s Democratic Senate primary.

Multiple news outlets called the race within 90 minutes of the polls closing, with only a fraction of the votes counted.

The victory was seen as a foregone conclusion after Platner’s primary opponent, Gov. Janet Mills, suspended her candidacy in late April, saying her campaign could not afford to continue.

Still, the final tally suggested that not all Mainers had embraced the political neophyte whose campaign was dogged by controversies, including the revelation that Platner had a Nazi Totenkopf tattoo on his chest for nearly two decades until he drew criticism for it on the campaign trail. He denied knowing it was a Nazi symbol.

Mills, who remained on the ballot, drew about one in five votes in the first 10% of ballots counted, according to the tally published by The New York Times.

Platner to face off against Republican Sen. Susan Collins

The result sets Platner up to face off in November against incumbent Republican Sen. Susan Collins, who has received substantial support from pro-Israel donors. The latest polls suggest a tight race.

“I’m humbled and proud to officially be your Democratic nominee for the US Senate to take on Susan Collins and the billionaire class she represents. Together, we will win this seat back for working Mainers,” Platner tweeted on Tuesday night. “Thank you, Maine.”’

Platner recently drew allegations of antisemitism 

While Democratic leaders officially threw their support behind Platner after Mills halted her campaign, many of them remained circumspect about him. Their balancing act grew more delicate in the final days of the primary race, as Platner drew allegations of antisemitism over his characterization of donations channeled to Collins by the pro-Israel lobby AIPAC and as he faced new allegations of misconduct toward women. (He said he had been a “far from perfect boyfriend” during some periods of his life but denied engaging in misconduct.)

Now, top Democrats will have to decide how hard to gun for Platner, who has become a standard-bearer in the party’s anti-Israel shift at a time when the chamber is narrowly divided.

They are already facing pressure to disavow him. “Chuck Schumer, the highest-ranking Jewish elected official in America, and every Senate Democrat propping up Platner’s campaign, should be ashamed,” the Republican Jewish Coalition said in a statement after the polls closed. “Their continued support of Graham Platner, who wore the symbol of Hitler’s SS on his chest for 18 years is an outrage. Schumer must withdraw his support immediately.”
