As an emboldened socialist wing of the Democratic Party gains traction across New York City in the aftermath of Mayor Zohran Mamdani’s victory, Jewish leaders and moderate officials are bracing for the possibility of multiple upsets in key House races that could reshape the ideological orientation of the state’s congressional delegation.
Three races have drawn heightened attention in recent weeks, including a marquee House contest playing out largely in progressive Brooklyn where Rep. Dan Goldman (D-NY) is seeking to fend off a serious challenge from former New York City Comptroller Brad Lander. Meanwhile, in upper Manhattan and the Bronx, Rep. Adriano Espaillat (D-NY) is facing what looks like an increasingly credible challenge from an anti-Israel organizer. And in the race to replace retiring Rep. Nydia Velazquez (D-NY), her favored primary candidate is struggling to compete against a democratic socialist endorsed by Mamdani.
“If you have two socialists and Brad Lander” who are elected, “that’s a real move to the left — and it’s a lot of people who are bringing down the seniority of the congressional delegation,” said Chris Coffey, a New York City Democratic strategist not involved in the races. “That is probably the biggest shift we’ve seen at the congressional level in generations,” he told Jewish Insider, adding that there are “a lot of ifs baked into that.”
A recent public poll showing Goldman trailing badly behind Lander underscored how an emboldened far left is asserting itself in a race that is hinging in large part on the candidates’ differences over Israel. The independent survey, released last week by Emerson College, strongly indicated that Goldman is in serious trouble in the closely watched June 23 primary, lagging badly behind Lander, who held a commanding 57% of the vote.
Goldman, a pro-Israel Democrat who gained prominence as an outspoken critic of President Donald Trump, touts a relatively progressive record on domestic issues like healthcare, climate policy and immigration. But as he seeks a third term, Goldman has faced backlash from left-wing activists over his continued support for U.S. funding to Israel, which Lander, notably endorsed by Mamdani, has vowed to end, even for missile defense.
In a rare convergence on Middle East-related issues, the candidates opposed a successful effort this week to implement a boycott of Israeli products at a high-profile local food cooperative in the Park Slope neighborhood of Brooklyn, which sits in the district. (In a sign of the times, the boycott vote passed by a 2-to-1 margin.) But they otherwise disagreed on whether the measure was antisemitic, as Goldman and other Jewish community activists, including an influential rabbi in the district, had described the divisive effort.
Both Goldman and Lander are slated to address Jewish community concerns on June 7 during off-the-record town hall events at Congregation Beth Elohim, a Reform synagogue in Park Slope that is led by that rabbi, Rachel Timoner, according to an email recently sent to members. They will answer questions from congregants independently in the back-to-back, hour-long forums.
Despite tensions over Israel, some strategists note that Lander’s dominance in the progressive district covering sections of Brownstone Brooklyn and Lower Manhattan can be attributed to his standing as a popular former councilman and citywide elected official who also ran for mayor last cycle — a level of name ID that marks him as a sort of de facto incumbent.

But other races have also sharply demonstrated how anti-Israel sentiment is fueling the rise of candidates endorsed by the Democratic Socialists America’s New York City chapter. The group, which has championed anti-Zionism as a core element of its platform, is now backing challengers in two high-profile congressional primaries as well as some down-ballot races for seats in the state Legislature.
The closest race, for an open House seat spanning parts of Brooklyn and Queens, pits Claire Valdez, a democratic socialist assemblymember who is known for her anti-Israel activism, against Antonio Reynoso, the progressive Brooklyn borough president boasting establishment support from the outgoing incumbent, Velazquez, and the state attorney general, Letitia James, among other elected officials and groups.
But even as Reynoso entered the race in a favorable position, well-known to voters for his reputation as a more traditional progressive, he has struggled in his campaign to gain traction, recently calling himself an underdog, thanks to Valdez’s support from Mamdani paired with the grassroots organizational muscle of a resurgent DSA. A recent poll showed Valdez narrowly leading Reynoso by two points, with 23% of the vote, even while she is comparatively new to the district as a first-term state lawmaker.
Valdez’s favorable position has come as she has made opposition to Israel a primary focus of her campaign, while facing some scrutiny over her decision to sit for a friendly discussion earlier this month with a Twitch streamer who was once suspended from the platform for calling Jews a “demonic ethnicity.” Her campaign did not respond to a request for comment concerning the interview.
In a separate House primary in upper Manhattan as well as parts of the Bronx, Jewish leaders have begun to raise alarms about an insurgent challenger to Espaillat, a veteran incumbent who, like Goldman, is backed by the pro-Israel group AIPAC. In the final weeks of the race, he is now facing what Democratic strategists say is an increasingly serious threat from Darializa Avila Chevalier, a DSA-endorsed organizer who helped lead campus anti-Israel demonstrations at Columbia University.
“Folks seem to be getting very nervous,” one Jewish leader following the race told JI, echoing others who relayed similar concerns about the contest as it enters its closing stretch.
An internal campaign poll conducted in March, for instance, put Avila Chevalier at 28% among primary voters, with Espaillat at 42%, a poor showing for an incumbent who has held office for close to a decade. Political observers suggested the race could be closer as the primary nears and Avila Chevalier rides a wave of anti-establishment, leftist sentiment now shaping several races across the country where the DSA is involved.
In addition to backing an arms embargo on Israel and efforts to boycott the Jewish state, both Avila Chevalier and Valdez pledged to “refrain from any affiliation with the Israeli government and Zionist lobby groups, including but not limited to AIPAC, J Street, or DMFI,” according to DSA questionnaires reviewed by JI.
Justice Democrats, the far-left group that has frequently targeted incumbents, has also endorsed both candidates and is now spending to boost their campaigns. On Wednesday, it dropped $260,000 on ads to help boost Avila Chevalier — suggesting it sees the race as in play. The group also made its first foray into Valdez’s primary this week, according to filings, spending $11,000 on digital ads to prop up her bid.
Reynoso and Espaillat, meanwhile, can expect seven figures spent independently on their behalf in the coming weeks, a Democratic operative familiar with the matter told JI, but did not disclose the source of such funding.
The upcoming expenditures foreshadow what is shaping up to be a bitterly contested fight between the Democratic establishment and the far left now seeking to supplant it.
Still, there are signs that the far left is struggling to gain traction outside of deeply progressive districts. For example, Rep. Ritchie Torres (D-NY), a pro-Israel stalwart facing a challenge from former state lawmaker Michael Blake, who has made opposition to AIPAC a key part of his messaging, is expected to prevail. A recent poll showed Torres with a commanding 60% of the vote share, far outpacing Blake, who held just 15% in the Bronx-based district.
Torres’ position “shows that if you are actually working hard in your district and are there and present and delivering, then you should be OK,” Coffey, the Democratic strategist, told JI, noting that the congressman also developed a positive relationship with Mamdani, despite their disagreements on Middle East policy.
Hank Sheinkopf, a veteran Democratic strategist in New York City, characterized the DSA’s strategy as part of a “long-term plan” to “take over legislatures” across the country and influence foreign policy at the congressional level, as other far-left candidates have made inroads in key House races in Philadelphia and Denver. “New York is just the beginning,” he told JI.
Lander has been criticizing Goldman for not fighting against Trump, even though he led impeachment efforts against the president

Rep. Dan Goldman (D-NY), left, is joined by New York City Comptroller Brad Lander during a news conference outside the Metropolitan Detention Center in the Sunset Park neighborhood of Brooklyn on Tuesday, Aug. 16, 2022.
The hotly anticipated primary matchup between outgoing New York City Comptroller Brad Lander and Rep. Dan Goldman (D-NY) was widely expected to be a bellwether race that would test the strength of pro-Israel sentiment within the Democratic Party.
Featuring two prominent Jewish New Yorkers with sharply opposing views on the Middle East, the race notably pits Lander, an outspoken critic of Israel and its war in Gaza, against Goldman, a more moderate incumbent viewed as a strong defender of the Jewish state.
But nearly a week after announcing his challenge, Lander, the progressive New York City comptroller, is so far tiptoeing around such differences, even as they are arguably the driving contrast in the primary. Instead, he has more actively emphasized a message that is casting Goldman as ineffective in countering President Donald Trump — declaring it is “time for fighters” and “not folders” in Congress.
His top surrogates — including a range of vocal Israel critics including Sens. Elizabeth Warren (D-MA) and Bernie Sanders (I-VT) and Zohran Mamdani, the mayor-elect of New York City — have made no mention of Middle East policy in their statements endorsing his campaign to represent New York’s 10th Congressional District, which covers Lower Manhattan and a swath of northwest Brooklyn.
“We need more fighters in Washington now more than ever, and Brad is a fighter,” Warren said last week, adding that Lander has “the grit to not just win this race, but deliver for working families.”
Such comments, however, have failed to note that Goldman, who was elected to Congress in 2022, is recognized as a leading Trump antagonist, having served as the top prosecutor in the president’s first impeachment case. Like Lander, he has frequently confronted the Trump administration on a range of issues including its immigration agenda. Last week, for instance, Goldman seized the spotlight during a fiery House hearing in which he clashed with Kristi Noem, the Homeland Security secretary — accusing her of illegally deporting asylum seekers in a grilling that drew headlines and social media virality.
Warren’s team did not respond to a request for comment when asked why she was not satisfied with Goldman’s record opposing Trump and his administration’s policies.
The early effort by Lander and some of his allies to employ rhetoric focused largely on fighting Trump has obscured how Israel is the clearest dividing line in the race — raising questions about Lander’s strategy as he seeks to shape a narrative Goldman’s supporters have dismissed as a misdirection. Rep. Nancy Pelosi (D-CA), in a statement last week, countered that her colleague is one of the “best members” she has “ever served with” and said he “is exactly the right fighter for this moment.”
With opposition to Trump likely a major motivating force for midterm voters, Lander is now facing scrutiny over his attacks targeting a two-term incumbent who has long staked his reputation on effectively battling the president. Meanwhile, in the wake of Israel’s recent ceasefire with Hamas, it remains to be seen if Gaza will continue to be an animating issue heading into the June primary election that is already shaping up to be a heated and expensive race.
Goldman, a Levi Strauss heir whose estimated net worth is up to $250 million, spent nearly $5 million of his own money during his first primary bid three years ago, when he narrowly prevailed in a crowded field of progressive rivals who split the vote. Lander has also targeted Goldman’s personal wealth, saying that the “oligarchy” should not “be able to buy a seat in Congress.”
Even as Lander, a former longtime city councilman from Brooklyn, touts high-profile support from the Senate, House progressives have for their part so far stayed on the sidelines.
Rep. Alexandria Ocasio-Cortez (D-NY), an Israel critic who backed Lander’s comptroller bid in 2021 and called him a “talented hero” after his arrest by federal agents at an immigration courthouse last June, said she is “not weighing into that race right now,” echoing other like-minded lawmakers who also declined to take sides in the looming primary.
While Lander has long identified as a progressive Zionist, he has been outspoken in criticizing Israel’s conduct in Gaza, accusing the country of war crimes and ethnic cleansing. He has additionally called for conditioning U.S. aid to Israel, a measure Goldman has rejected.
“What Lander is counting on now is the sentiment of the moment, which is further to the left and more anti-Israel,” Hank Sheinkopf, a veteran Democratic consultant in New York City, told Jewish Insider in a recent interview.
In a speech before the mayoral election, where he rose to prominence as a top surrogate for Mamdani after losing his own primary bid, Lander advocated for building a “coalition of anti-Zionists and liberal Zionists,” seeking to unify opposing factions to end “the horrors in Gaza.”
Goldman, for his part, chose not to endorse Mamdani, citing concerns about his approach to Israel and rising antisemitism, but he has said he looks forward to working with the mayor-elect on promoting his affordability agenda.
“What Lander is counting on now is the sentiment of the moment, which is further to the left and more anti-Israel,” Hank Sheinkopf, a veteran Democratic consultant in New York City, told Jewish Insider in a recent interview.
Still, in the days after launching his campaign, Lander has sent mixed signals about how he plans to highlight differences with his opponent on Israel.
In his campaign announcement video released last Wednesday, for example, he took a thinly veiled jab at Goldman in vowing not to do “AIPAC’s bidding,” referring to the increasingly demonized pro-Israel group, but did not mention the incumbent by name.
Lander told The New York Daily News in an interview last week that he views contrasts over Gaza as ancillary to their approaches to confronting the Trump administration, drawing raised eyebrows from observers who noted that hitting Goldman on his strongest issue avoids addressing a more salient tension over Middle East policy.
“On this issue, we have some disagreements,” he said of Israel, “but the core rationale is because it’s time for fighters not folders,” Lander elaborated on his approach to the race.
One Jewish community leader supportive of Goldman expressed frustration at the logic behind Lander’s challenge. “I’m just pissed that there’s not a single thing they can point to what Goldman isn’t doing right other than being pro-Israel,” he told JI, speaking on the condition of anonymity to address a sensitive subject.
During a campaign kickoff event in Brooklyn last week, Lander accused Goldman of failing to hold Israel accountable for its behavior in Gaza, saying “only I, of the two of us, recognize that Netanyahu’s leveling of schools and hospitals and the destruction of Gaza was a war crime,” in reference to the Israeli prime minister. He also reiterated that New Yorkers “don’t want elected officials who do AIPAC bidding in a district that recognizes that our safety and our freedom is bound up together.”
Lauren Hitt, a spokesperson for Lander’s campaign, disputed criticism that he is avoiding Israel as a top issue. “Brad literally called out AIPAC in his launch video, so safe to say he will continue to spend quite a bit of time discussing Israel in this race,” she said in a statement to JI on Friday.
On Friday, Lander also said on social media that, if he were a member of Congress, he would introduce a resolution censuring Rep. Randy Fine (R-FL) over his recent incendiary comments calling for Muslims to be “destroyed.” Lander, without directly citing his opponent, also noted he would “not have voted with Republicans” to censure Rep. Rashida Tlaib (D-MI) over incendiary comments against Israel during the Israel-Hamas war in 2023, as Goldman himself had done.
Hours later, Goldman also denounced Fine in an X post for remarks assailing Muslims as “barbarians,” calling the statement “despicable and unacceptable” and saying he “must apologize and retract this tweet immediately.”
Lauren Hitt, a spokesperson for Lander’s campaign, disputed criticism that he is avoiding Israel as a top issue. “Brad literally called out AIPAC in his launch video, so safe to say he will continue to spend quite a bit of time discussing Israel in this race,” she said in a statement to JI on Friday.
“Brad will also speak to the other issues concerning NY-10 voters, including affordability — another topic where the heir to the Levi Strauss fortune is out of step with the district’s experience. NY-10 voters don’t need a representative that’s palling around with Don[ald Trump] Jr. in the Bahamas, they need someone who understands and represents their views,” Hitt added, referring to an October social media post in which Trump’s son sarcastically thanked Goldman for his “kind words” about the president’s ceasefire and hostage deal during the government shutdown.
For now, it is unclear how AIPAC and pro-Israel groups more broadly are assessing the matchup — and if they will choose to engage in the primary. A spokesperson for AIPAC declined to weigh in.
In 2022, AIPAC disclosed after Goldman had won his primary that its super PAC, United Democracy Project, had quietly contributed at least $350,000 to a separate group established near the end of the race to fund a series of attack ads against Yuh-Line Niou, a far-left rival who had drawn controversy for voicing alignment with the Boycott, Divestment and Sanctions movement targeting Israel.
One pro-Israel consultant, who was granted anonymity to address a sensitive topic, suggested “AIPAC’s involvement in the race would probably be a negative against Goldman.” Mamdani, an ally of Lander who has long been a fierce critic of Israel, performed well in the district — where Goldman’s views on Israel have faced backlash from left-wing voters.
Democratic Majority for Israel, which is backing Goldman, had been wary of a one-on-one contest with Lander, whom polling has shown is a strong opponent, according to a person familiar with the group’s discussions. Lander’s early consolidation of progressive support helped to push two other rivals on the left not to run in the race, effectively clearing the field for the outgoing comptroller. A spokesperson for DMFI did not respond to requests for comment regarding its plans.
Goldman, meanwhile, said in an interview with a local news outlet last week he welcomes Lander’s challenge but is “not really thinking about” the race “right now.” A campaign spokesperson said that he is “focused on stopping” Trump and “will deal with Brad and other challengers in the new year,” when he is “planning to roll out a flood of” endorsements from fellow House members.
Despite differences over Israel, Goldman is also endorsed by J Street, a progressive Israel advocacy group that has long been close to Lander. A spokesperson for J Street told JI in a statement the group is “proud” to back Goldman and “we deeply value his pro-Israel, pro-peace and pro-democracy leadership.”
“Dan has a progressive record,” said Chris Coffey, a Democratic strategist. “It’s not always as far left on Israel as Brad, for sure, and that is one of the things that differentiates them on policy.” Israel, he added, “could be a defining issue in this race,” regardless of Lander’s messaging efforts to prioritize Trump.
“We are also grateful for our years-long friendship with Brad Lander, who is a vocal leader for our values. We know that the issue of peace is close to both of their hearts,” the spokesperson continued. “Ultimately, it is up to the district to determine who they want to represent them in Congress, and we are glad to see two J Street-aligned voices in this race.”
A top J Street official, speaking on background to address the primary, confirmed the group will not be engaging materially in the race as it is satisfied with both candidates’ records. “I expect our donor base will give to both,” the official told JI. “There’s definitely a split of opinion on this race, to say the least.”
“Dan has a progressive record,” said Chris Coffey, a Democratic strategist. “It’s not always as far left on Israel as Brad, for sure, and that is one of the things that differentiates them on policy.” Israel, he added, “could be a defining issue in this race,” regardless of Lander’s messaging efforts to prioritize Trump.
Lander, for his part, could also face backlash from far-left activists in the district who have bristled at his identification as a progressive Zionist and have taken issue with his investments in an Israeli arms producer as comptroller, even as he chose to cease holdings of Israel bonds during his four years in office.
The Democratic Congressional Campaign Committee, which is focused largely on winning back the House in next year’s midterms, declined to comment on the primary, though it has traditionally backed incumbents.
Locally, a political advocacy group in the district called Brooklyn BridgeBuilders, which is dedicated to fighting antisemitism and anti-Israel sentiment, is planning to support Goldman and is currently in the process of formalizing its strategy, according to Ramon Maislen, its CEO.
“The decision to challenge a highly effective liberal Jewish incumbent is incredibly fraught,” Maislen, a Jewish community activist who lives in Park Slope, told JI. “Dan is someone who has been unwavering in taking on Trump, defending our democracy and standing with the Jewish community.”

What You Should Know
A QUICK WORD WITH JI’S MATTHEW KASSEL
In previous mayoral elections in New York City, a candidate’s meeting with a controversial imam who was listed as an unindicted co-conspirator in the 1993 World Trade Center bombing — and who has stridently opposed homosexuality and condemned America as “filthy” and “sick,” among other extreme remarks — might be expected to meaningfully dent support for his campaign.
But even as Zohran Mamdani, the Democratic nominee, has drawn criticism over his recent meeting with Siraj Wahhaj, a Brooklyn imam who leads Masjid at-Taqwa in Bedford-Stuyvesant, political experts say that such backlash is unlikely to influence the outcome of the Nov. 4 election.
That Mamdani, a 34-year-old democratic socialist and Queens state assemblyman, appears poised to withstand scrutiny over his relationship with Wahhaj, which he has defended, underscores how dramatically the political environment has changed in New York City — where the emotional resonance of the 9/11 terror attacks have long played a central role in campaigns and elections.
“Dead cops and firefighters don’t seem to matter much these days,” Hank Sheinkopf, a Democratic consultant who is leading an anti-Mamdani super PAC, told Jewish Insider on Monday. “I think it’s a generational question,” he added, noting that “the people who are voting for” Mamdani “weren’t even born on Sept. 11.”
While he said that Mamdani’s meeting “isn’t helpful” and could ultimately push some voters concerned about public safety to instead back one of his rivals — including the Republican nominee, Curtis Sliwa, or former New York Gov. Andrew Cuomo, running on an independent line — “the question is whether they can generate a vote,” according to Sheinkopf.
“That’s not clear yet,” he explained, saying the controversy could be “buried under” Mamdani’s continued focus on affordability, which helped drive his upset over Cuomo in the Democratic primary in June.
Both Cuomo and Sliwa have attacked Mamdani for the meeting, with the former governor zeroing in on Wahhaj’s history of homophobic comments — including remarks in which the imam called homosexuality “a disease.”
Mamdani, who would be the first Muslim mayor of New York City if elected, has dismissed criticism of his Friday meeting with Wahhaj — whom he praised as “one of the nation’s foremost Muslim leaders and a pillar of the Bed-Stuy community for nearly half a century.”
TRIP TALK
Vance takes center stage in Trump effort to keep Gaza ceasefire on track

Vice President JD Vance landed in Israel on Tuesday with the charge to lead efforts to stabilize the fragile ceasefire in Gaza and assist in the implementation of the second phase of President Donald Trump’s peace deal, Jewish Insider’s Washington reporter Matthew Shea reports. The vice president will now step into the conflict, visiting Israel at an important juncture as the Trump administration looks to avoid another breakdown into renewed hostilities and ensure full compliance with the deal. “Hamas is going to fire on Israel. Israel’s going to have to respond, of course. There are going to be moments where you have people within Gaza that you’re [not] quite sure what they’re actually doing. But we think it has the best chance for sustainable peace,” Vance told reporters on Sunday, referring to the peace proposal.
Continuous engagement: The decision to dispatch Vance to Israel is a sign of the Trump administration’s continued engagement in the Middle East after securing the hostage-release deal, according to experts. “We are in a moment of really intense American engagement and influence that have got us to a stage one that no analyst a month ago would have told you was possible, and so there is a moment of opportunity here,” said John Hannah, a senior fellow at the Jewish Institute for National Security of America. “In order to be sustained, it’s a ceasefire and peace process that is going to require intense and continuous U.S. engagement at the most senior levels.”
