Democratic primary voters in Florida’s newly drawn 25th Congressional District are choosing on Tuesday between an anti-Zionist member of the Democratic Socialists of America and one of Israel’s staunchest supporters in Congress.

The race offers a test of whether the Democratic Party’s progressive insurgency can extend to a district that includes Delray Beach, Boca Raton, and Miami Beach, and an electorate that is roughly 25% Jewish, highlighting the party’s widening divisions over Israel.

Redistricting has transformed what had been solidly Democratic territory into a district US President Donald Trump would have carried in 2024. The new lines pit Oliver Larkin, a DSA member who has accused Israel of genocide and called for ending US military aid to the country, against Jared Moskowitz, a two-term congressman who backs continued US military aid even as support for it has eroded within his party.

Polling from Moskowitz-aligned firms has shown him with a lead of 30-plus percentage points, while a more recent poll from a Larkin-aligned outlet this month put the two in a statistical dead heat.

Larkin’s language has alarmed some Jews, including his labeling of modern-day Israel as a “religious supremacist” country and his call for Israel to become a “secular” state. “I do not support a religious supremacist regime, whether it be in Israel or Saudi Arabia, or any other country,” Larkin told Fox News.

Larkin backs Mamdani on goal of arresting Netanyahu

Larkin supports a complete arms embargo on Israel, and told JTA that that should be “the minimum standard for anyone claiming to support democracy.” Asked by Fox News if he supports selling defensive weapons to Israel, Larkin responded, “I do not make a distinction between offensive and defensive weaponry.” He also backed New York City Mayor Zohran Mamdani’s goal of arresting Prime Minister Benjamin Netanyahu. Larkin doubled down after Mamdani backed down from the stance, saying, “I believe that the United States, any federal or otherwise law enforcement entity that has the legal jurisdiction to arrest Benjamin Netanyahu for his war crimes - that should be enforced.”

Larkin has courted support from left-wing, anti-Zionist Jews who support his platform and says that he has spoken out against antisemitism on the campaign trail.

“Our campaign believes in collective liberation for all people, and that includes the liberation of Jewish South Floridians and Jewish people the world over from antisemitism,” Larkin said in a statement to the Jewish Telegraphic Agency. He said that there is a rise in fascism across the US and that we “must recognize the link between antisemitism, Islamophobia, anti-Black racism, xenophobia, transphobia, and more and build a coalition to unite together to defeat these forces.” 

Larkin said he supports a “one-state solution with equal and democratic rights for all people.”

Progressive, pro-Palestinian candidates with similar platforms have won the Democratic nomination this midterm cycle in deep-blue districts around the country. Larkin, who worked on Vermont Sen. Bernie Sanders’ 2016 presidential campaign, is betting he can match their success even in a heavily Jewish district that leans more to the center.

Moskowitz, who is endorsed by AIPAC and Democratic Majority for Israel, outright accused Larkin of fueling antisemitism, telling the Sun Sentinel editorial board in a letter that his opponent “has embraced the support of individuals and organizations that have repeatedly trafficked in antisemitic rhetoric and hostility toward the Jewish community.”

Last month, a Boca Raton rabbi encouraged Republican congregants to register as Democrats so they could cast their votes for Moskowitz. The far more moderate Democrat has refused to debate Larkin, saying that his opponent is contributing to antisemitism.

Moskowitz has also claimed that Larkin is “running against me solely on my religion.” The Sun Sentinel board rated Moskowitz’s claim “demonstrably untrue” and, in an unusual move, said it would not endorse him for reelection after he declined a joint interview with Larkin. The paper decried what it described as Moskowitz’s “lack of respect for voters.” Moskowitz’s campaign did not respond to a JTA request for comment.

Moskowitz has outraised Larkin 11-to-1, according to local media estimates. The American Israel Public Affairs Committee has raised $667,200 of Moskowitz’s $2.5 million through June 30, according to campaign finance analyses done by the website Open Secrets.

Anti-Zionist groups rooting for Larkin

Donna Nevel, a member of the South Florida chapter of the anti-Zionist group Jewish Voice for Peace, believes Larkin can win.

“There are thousands and thousands of us, from Jewish communities and all across South Florida, who are doing everything we can to make sure that Oliver will be our congressperson,” Nevel said to a cheering crowd, during a fundraiser held in New York City earlier this month.

She also said that “many Zionist organizations think that South Florida is their backyard.” She continued, “And we say, ‘Hell no!’”

In an email to JTA, Nevel said there are a “large and growing” number of Jews in the district supporting Larkin, including “well over a hundred Jewish canvassers on a regular basis.” Larkin joined a JVP-hosted Shabbat dinner with Michigan Rep. Rashida Tlaib and Florida’s left-wing US Senate candidate Angie Nixon on Friday.

Larkin has said that we “should not be supporting or allowing AIPAC to influence our elections.” He told the South Florida Sun Sentinel that the group has a “corrupting influence” and that it only supports Congress members “on the condition, in my estimation, that they support wholesale US military aid to Israel.”

Left-wing streamers Hasan Piker - a staunch Israel critic who’s drawn antisemitism accusations - and Michael Beyer, who was suspended from Twitch after calling Jews a “demon ethnicity,” have both fundraised for Larkin.

Asked about their support, Larkin told the Sun Sentinel that both figures have used “language that I personally have not used and will not use,” and said that as a candidate it is important “that I speak in respectful terms and based in fact.”

“But I believe that when those individuals have made those references it’s been towards members of the Israeli government,” Larkin said, as well as Israeli settlers in the West Bank.

“So certainly they’re not politicians, and they don’t speak in political terms, and I don’t condone language that dehumanizes any individual,” he said. “I do think that they have legitimate criticism - even if it is rather unvarnished in how they convey it - of what the Israeli government has done.”
