Rep. Dan Goldman (D-NY), a pro-Israel Jewish Democrat who was unseated in a bitter primary on Tuesday, warned in his concession speech that antisemitism “will ultimately be the undoing of our democracy if we all don’t lean in and speak out.”

“Jews have given back so much to this country,” the two-term lawmaker said. “As history has taught us, antisemitic tropes and stereotypes, some of which I heard personally on this campaign, will ultimately be the undoing of our democracy if we all don’t lean in and speak out — even if it’s not politically expedient.”

Goldman, who was resoundingly defeated by Brad Lander, the former city comptroller backed by New York City Mayor Zohran Mamdani, faced blowback during the campaign over his support for Israel and ties to the pro-Israel lobbying group AIPAC — some of which invoked hostile antisemitic rhetoric.

In the final days of the primary, a Brooklyn coffee shop Goldman patronized wrote in an incendiary online post it was banning him over his pro-Israel views, calling him a “genocide enabler” and saying his purchase “probably” came from AIPAC — which endorsed him but did not engage directly in the race.

The Department of Justice’s Civil Rights Division said Monday it had opened an investigation into the cafe for discrimination, though Goldman clarified he did not believe the incident warranted legal scrutiny.

“Every day I tried to approach this job with integrity, with seriousness and courage to stand up for what is right, even when it was not politically expedient,” the ousted congressman said in his concession speech, in an apparent reference to his defense of Israel over the course of the primary.

Goldman, a former federal prosecutor who rose to national prominence as the lead counsel during President Donald Trump’s first impeachment, shared a range of progressive policy views with Lander, a fellow Jewish Democrat who identifies as a progressive Zionist. 

Despite their agreements on several key issues, the race ultimately became a referendum on support for Israel in the Democratic Party and Goldman’s refusal to disavow his Zionist ideals. He lost by more than 30 points, with 90% of the vote tallied as of Wednesday.

Lander, who accused Israel of genocide in Gaza and called for ending U.S. aid to the Jewish state, largely aligned his campaign with the anti-Zionist far left as he touted his endorsement from Mamdani, a key ally who also played a decisive role in helping elevate two democratic socialists with records of vocal anti-Israel activism to the nomination on Tuesday.

In his victory speech, Lander, who won a decisive 66% of the vote in New York’s 10th Congressional District, praised Goldman “for how he responded to some of the toxic rhetoric that he and his staff faced over the past couple days,” saying his opponent had acted “with grace and with gratitude.”

“That is something we need more of in our politics,” Lander added. 

Even as he raised alarms about antisemitism on the left, Goldman called on his supporters to “remember the enemy to all that we want and all that we hope for is in the White House, not in our own party.”

The Democratic Party, Goldman said, “has always been at its strongest when it has welcomed a broad coalition of voices united by those shared democratic values of equal rights, social justice, human rights.”

“We have never required unanimity of opinion to stand together against the forces that truly threaten our democracy,” he argued in his concession speech. “And we should not demonize, or push away, anyone who shares our mutual goals.”

A spokesperson for Goldman did not respond to a request for an interview on Wednesday.
