Maine Senate hopeful Graham Platner is a woman-hater who once twisted an ex-girlfriend’s arm — and fantasized about killing people and raping intruders, according to a slew of women who’ve come forward to out his disturbing behavior.

The Democrat candidate, who’s been endorsed by progressives like Sens. Elizabeth Warren and Bernie Sanders, as well as Senate Minority Leader Chuck Schumer, also boasted about having a Nazi tattoo, calling it “my Totenkopf,” one ex recalled — contradicting his October claim that he thought the ink was merely a “terrifying skull and crossbones.”

A Totenkopf is the image adopted by Hitler’s Schutzstaffel, or SS, the murderous group that carried out the bulk of Nazi violence in the Holocaust.

Three of Platner’s ex-girlfriends recounted their troubling time dating the Marine veteran to the New York Times, with the women describing him as someone who “hated women” and would call them “hatchet wounds,” in the latest scandal to dog his campaign.

“He said this a lot: If anybody ever broke in here, I would rape them,” said 40-year-old Lyndsey Fifield, who dated Platner from 2013 to 2015.

“He was like, ‘I would rape them to show them that I’m dominant,’” she added.

Platner, 41, also once twisted Fifield’s arm during an argument — before he shoved her in a bedroom and wouldn’t let her leave until she was “calm,” she claimed.

“It hurt,” Fifield told the Times. “It didn’t cause an injury, it didn’t break my arm.”

Platner disputed Fifield’s claims, referring to Fifield — a Republican campaign worker from Virginia — as a “lifelong G.O.P. operative who’s dedicated her career to electing Republicans.”

But Fifield brushed off Platner’s response – insisting her time with him was so disturbing that she would speak up no matter what party he was running under.

“I know it looks like a bitter ex-girlfriend Republican trying to take down a Democrat — it has nothing to do with that,” she said. “If he was running as a Republican, I would be doing this exact same thing.”

And the arm-twisting incident wasn’t the only time she said Platner got physical with her – Fifield claimed he would frequently manhandle her around the shoulders, sometimes with enough force to leave marks.

Another time, he forced her out of a cab she didn’t want to leave, pulling her by the wrist, she claimed. But, he “never hit me, he never punched me,” she said.

Platner would also make violent comments in addition to his twisted boasts about rape – often while he was sharpening an axe as he watched TV, with Fifield claiming Platner talked about killing people who might be a threat to him.

Fifield also provided 2016 diary entries and texts from after her break-up with Platner – long before he was considering a political career – to back her claims about the toxic relationship.

“DO NOT CALL GRAHAM,” one friend wrote to Fifield by text, while a diary entry Fifield wrote referred to Platner as “the most toxic literally abusive man on earth who destroyed my life.”

Platner denied both abusing any exes and lying about knowing the meaning behind his Nazi symbol tattoo in his first major interview on Thursday night since the sexting scandal broke.

He called the accusations “politically motivated” on on MS NOW’s “All in with Chris Hayes.”

The scandal is just the latest to follow Platner, who announced his run to unseat Sen. Collins in August and faces Maine’s primary vote to win the Democratic nomination on June 9.

A slew of horrifying posts Platner made on Reddit for years emerged within months of his campaign kickoff, with the candidate being seen disparaging women, rape victims, minorities, veterans, cops and working-class voters online.

He was then exposed for the vile Nazi tattoo on his chest which he got while on leave with the Marines in 2007 — but insisted he had no idea what it was in the nearly two decades before he opted to run for office.

Fifield also claimed that explanation was a blatant lie, telling the Times that Platner confessed to getting the Totenkopf explicitly because of its murderous origins.

“He would joke about it being a Nazi tattoo,” she said Platner explained. “They were like a death unit, they were killers.”

“They literally, deliberately, selected it because it was relevant to their military unit,” she added. 

Platner’s controversies mounted last weekend – after months of telling the public there were no more skeletons in his closet and insisting the same thing to Democrat leaders this week – when he was exposed by the Wall Street Journal for sexting multiple women on seedy hookup app Kik while he was married.

His wife Amy Gertner — who flagged her hubby’s creepy behavior to his own campaign last year — took to social media within days to acknowledge marital struggles, but stood by her husband and said they’d worked through them.

The pair married in November 2023.

Platner has also explained some of his behavior was a product of PTSD he suffered from his combat tours in Afghanistan.

“I’ve been open about what was a very dark period of my life where I struggled with undiagnosed PTSD, too often self medicated with alcohol, and was a far from perfect boyfriend,” Platner told the Post in a statement. 

“I take responsibility for all of that, and wish I had been better. Any characterization beyond that is false, and I believe, politically motivated,” he added. “I’m not proud of who I was then, but I am proud of the work I’ve done since, and the movement we are building in Maine.”

But the texting scandal – and Platner’s online posts — jibed with other exes’ experiences, with some describing him as frequently cheating on them and speaking poorly about women.

“When I saw the old comments that he made online, I recognized a version of him that I had experiences with,” said 41-year-old Jenny Racicot, a Maine Democrat who dated Platner in 2019 and 2021.

“I was like, that makes sense,” Racicot told the Times. “This person does not respect women.”

Fifield also called Platner “cavalierly contemptuous of women’s emotions, of our ‘weakness,’” and said his online behavior “reminded me of just how much he hated women.”

Several women who dated Platner, however, painted a different picture of him and said they never felt threatened by him.

“He was a great boyfriend,” said 36-year-old Carol Lemp, who dated Platner in 2013.

“He was super kind, very nice, fun,” she said, adding that he was a “gentle giant.”
