Three Progressive Candidates Win New York Democratic Congressional Primaries, Ousting Two Incumbents
On June 23, 2026, all three candidates backed by New York City Mayor Zohran Mamdani won their Democratic congressional primaries, setting off a public fight over the direction of the national Democratic Party.
Summary
On June 23, 2026, voters in three New York City Democratic congressional primaries chose all three candidates Mayor Zohran Mamdani had endorsed. Former City Comptroller Brad Lander beat two-term incumbent Rep. Dan Goldman by roughly two-to-one in the 10th District. Community organizer Darializa Avila Chevalier narrowly defeated five-term incumbent Rep. Adriano Espaillat — chair of the Congressional Hispanic Caucus, the main group representing Hispanic members of Congress — in the 13th District. State Assemblywoman Claire Valdez won an open-seat primary in the 7th District. All three districts lean heavily Democratic, so the winners are effectively headed to Congress in November.[1][2][13]
All three winners are allies of Mamdani, New York City's first democratic-socialist mayor. He endorsed them even though national Democratic leaders openly objected. Goldman had been backed by House Minority Leader Hakeem Jeffries and Governor Kathy Hochul. Espaillat received over $2.8 million in outside advertising from pro-Israel super PACs — political committees that can raise unlimited money — and donors connected to AIPAC, a major pro-Israel lobbying organization.[4][5] The key campaign issues were U.S. military aid to Israel during the Gaza war, housing costs, and healthcare. The progressive challengers used those issues to draw sharp contrasts with incumbents they said were out of touch with their districts.[6][7]
The results put deep splits inside the Democratic Party on full display. Jeffries publicly downplayed the divisions but said he and Mamdani 'agree to strongly disagree.'[8] New York Attorney General Letitia James accused Mamdani of 'blowing up' the Democratic Party and compared the disruption to tactics used by MAGA.[9] In his concession speech, Goldman warned that 'antisemitic tropes and stereotypes, some of which I heard personally on this campaign, will ultimately be the undoing of our democracy.'[20] Republicans framed the results as proof the Democratic Party has moved toward socialism. The National Republican Congressional Committee called Mamdani's brand a 'bogeyman' useful in competitive swing districts — districts where either party could win — this fall.[10]
The core question under debate: Does a coalition that wins democratic-socialist primaries in safe urban districts represent the future of the whole Democratic Party? Or is it a regional movement that could hurt the party in competitive suburban districts — the ones that will decide who controls Congress in November 2026?
The Event
On the evening of June 23, 2026, all three candidates Mayor Zohran Mamdani endorsed won their Democratic congressional primaries in New York City. Brad Lander beat two-term incumbent Rep. Dan Goldman in the 10th District, taking about 65.8% of the vote to Goldman's 34%. The Associated Press called the race minutes after polls closed.[11] Darializa Avila Chevalier, 32, narrowly beat five-term incumbent Rep. Adriano Espaillat in the 13th District, which covers Upper Manhattan and parts of the Bronx.[12] State Assemblywoman Claire Valdez won an open-seat primary in the 7th District, defeating Brooklyn Borough President Antonio Reynoso for the seat left open by retiring Rep. Nydia Velázquez.[13] Goldman is at least the fifth House incumbent to lose a primary in the 2026 election cycle.[15]
Undisputed Facts
- Brad Lander won the NY-10 Democratic primary against incumbent Rep. Dan Goldman, getting roughly 65.8% of the vote to Goldman's 34%. The Associated Press called the race minutes after polls closed.[11]
- Darializa Avila Chevalier won the NY-13 Democratic primary over Rep. Adriano Espaillat — a five-term incumbent and chair of the Congressional Hispanic Caucus, the main group representing Hispanic members of Congress — in a narrow upset.[12]
- Claire Valdez won the NY-7 Democratic primary for an open seat, defeating Brooklyn Borough President Antonio Reynoso. Rep. Nydia Velazquez was not seeking re-election.[13]
- Goldman was endorsed by House Minority Leader Hakeem Jeffries and Governor Kathy Hochul; Mamdani backed Lander over those objections.[4]
- AIPAC — a major pro-Israel lobbying organization — and its affiliated super PAC network (political committees that can raise unlimited money) spent over $2.8 million in ads opposing Avila Chevalier and supporting Espaillat. Espaillat also received more than $140,000 in AIPAC-earmarked campaign donations.[5][22]
- Brad Lander left the Democratic Socialists of America in 2023 after the October 7 Hamas attacks. He describes himself as a 'liberal Zionist' who supports adding new restrictions on U.S. military aid to Israel.[14]
- If she wins in November's general election, Avila Chevalier would become the first Dominican-American woman elected to Congress. Espaillat was the first Dominican-American elected to the House.[12]
- Espaillat was also the first formerly undocumented immigrant to serve as a congressional lawmaker in U.S. history. He arrived in the United States from the Dominican Republic without documentation as a child before gaining legal status.[12][26]
- Candidates backed by the Democratic Socialists of America (DSA) also won multiple New York state Senate and Assembly races on the same night, extending the sweep beyond the three congressional contests.[18]
The Pressure
Strip away the moralizing and blame. What structural realities persist regardless of which narrative wins?
- The Urban Affordability Imperative
- The three districts that produced these results are among the most expensive, densely populated, and economically stressed urban areas in the country. New York City renters face some of the highest rent burdens in the nation. Gaps in healthcare access are severe. The primary voters in these areas tend to be younger and more economically anxious than the average Democratic primary voter nationwide. These structural conditions — not just Mayor Mamdani's endorsement — are what made progressive challengers viable in the first place. None of that changed on election night.[7][17]
- The Electoral Geography Imperative
- All three primary winners are nearly certain to win their November general elections — the districts are solidly and consistently Democratic. So these results matter almost entirely inside the Democratic Party: the real question is who controls the party's agenda in Congress, not how many seats each party holds. Republicans will keep their own seats regardless of which Democrats represent Upper Manhattan or Brooklyn.[1][13]
- The Outside Money Limit
- Despite over $2.8 million in outside advertising for Espaillat from AIPAC-affiliated super PACs and a surge of last-minute pro-Israel donations, the spending did not prevent his defeat. This continues a pattern from the 2022 and 2024 primaries, where heavy outside spending failed to protect incumbents who were significantly out of step with their primary voters on issues those voters cared most about.[5][23]
Material realityThree New York City congressional seats will shift from moderate or centrist Democrats to DSA-aligned progressives — without changing which party controls any seat, since all three were already held by Democrats. The shift will, however, add three reliably progressive votes to the Democratic caucus on issues like U.S. military aid to Israel, healthcare expansion, housing policy, and economic regulation. In a chamber where Democratic margins are thin, three additional left-wing votes could matter in caucus leadership elections, committee assignments, and procedural votes. Whether this model — a democratic-socialist mayor endorsing DSA-aligned challengers in safe urban districts — can work in competitive suburban swing districts is a question November will not fully answer.[1][2][4]
Narrative as a weaponFour distinct groups are actively shaping how this story gets told — and each wants something different from it. Republicans want every voter in America to read these results as proof that the Democratic Party has become a socialist party, turning three primary wins in Brooklyn into useful advertising in suburban Ohio. The DSA and Mamdani want the wins read as national proof that democratic socialism is not just tolerated but actively demanded by a rising voter coalition — a foundation for a 2028 presidential platform. The Democratic establishment wants the story treated as 'an internal disagreement in safe blue districts,' so it does not become ammunition in the midterms. Pro-Israel advocacy groups want the central narrative to address documented antisemitism in progressive political spaces and the safety of Jewish Democratic voters — a concern that even winning candidate Brad Lander partly validated when he called some campaign-trail rhetoric 'over-the-top toxic'[24] — and to frame their sustained spending as a principled defense of a long-standing U.S. foreign policy commitment, not simply an effort to protect a favored incumbent. Each of these framings captures something real; none captures the full picture.
How Each Side Sees It
Each major actor’s view — how it frames things, its underlying incentive, and how it’s materially affected. Tap a side to read it.
Frames it asMamdani and his allies say Tuesday's results were a clear message from working-class New Yorkers who are fed up with the status quo on three connected crises: unaffordable housing, a healthcare system that leaves millions without coverage, and a U.S. foreign policy they say is funding mass civilian death in Gaza. They say their agenda is not extreme — it reflects what a clear majority of Democratic primary voters in diverse, high-rent districts actually chose. On Israel, they directly reject the antisemitism charge: Lander is Jewish and calls himself a liberal Zionist. They argue that opposing U.S. military transfers to a government conducting a war that has killed tens of thousands of civilians is a moral stance, not a bigoted one. Mamdani declared that 'Democratic voters want change,' and his supporters say these wins prove that democratic socialism can win elections — it is not a political liability.[7][16]
WhyMamdani is building a national coalition to push the Democratic Party's congressional caucus and its policies to the left. Three more DSA-allied members in Congress give him more leverage over legislative deal-making, committee assignments, and the 2028 primary cycle — and raise his national profile as a possible future presidential candidate.[1][16]
Impact on themAll three candidates are headed to Congress. Mamdani showed that his endorsement carries real electoral weight, giving him influence in future primaries beyond New York. The DSA will have more members in Congress, strengthening its influence over caucus decisions on leadership and legislation.[1][7]
Frames it asThe Democratic establishment does not dispute these primary results. Instead, it frames its worry as a question of strategy for November and coalition math. Jeffries needs to win competitive suburban seats — in New York, Pennsylvania, and Michigan — that look nothing like Brooklyn's 10th District. Establishment Democrats have long blamed the 'socialist' label for hurting the party in those suburbs, however the candidates define the term themselves. The clearest example came in 2020, when establishment Democrats widely argued the 'defund the police' slogan cost the party swing-district seats — though left-wing analysts disputed that direct causal link, pointing out that none of the Democrats who actually lost competitive seats in 2020 had personally endorsed the slogan.[27] New York Attorney General Letitia James put it plainly: 'All of us are a little frustrated with the Democratic Party. But you don't blow it up. That's what MAGA has done.'[9] The establishment's core argument is not that the winners' values are wrong. It is that supporting challengers against incumbents backed by the House Minority Leader sends a message to every vulnerable Democrat that party loyalty offers no protection — making it harder to hold the coalition together and win a House majority.[8][9]
WhyJeffries needs a functioning caucus and a party brand moderate enough to win the swing seats required for a House majority. Hochul faces her own re-election in a state where party divisions could hurt her. Both have strong institutional reasons to keep the 'socialist' label from becoming the Democratic Party's national identity.[8][17]
Impact on themJeffries lost two congressional allies. His working relationship with Mamdani is visibly strained, even if both stay publicly civil. The key unknown in November is whether the new nominees can drive enough turnout among urban base voters to offset any loss of moderate crossover support in competitive precincts within these districts.[4][8]
Frames it asRepublicans argue these results show the Democratic Party's true direction — and they plan to say so in every competitive district this fall. Rep. Mike Lawler declared: 'The Democrat party has officially become the party of Zohran, AOC, and Bernie.'[10] The National Republican Congressional Committee (NRCC) called Mamdani's socialist brand a 'bogeyman' they could use against Democrats 'to truly show who is leading their party and the crazy policies they all support.' Republicans say this goes beyond a branding attack: the winning candidates hold specific policy positions — restricting U.S. military aid to Israel, Medicare for All, and democratic socialist governance — that polls consistently show most voters in competitive suburban and rural districts oppose on the substance, not just as unfamiliar labels. Their broader argument is that even moderate Democrats in swing districts can be forced to answer for which faction is setting their party's direction in its own primaries. President Trump also cheered Goldman's defeat.[10][19]
WhyThe NRCC wants to hold and expand the Republican House majority by portraying the entire Democratic Party as captured by the socialist left. High-profile primary sweeps in New York hand them ready-made advertising material at no cost.[10]
Impact on themRepublicans gain a powerful national narrative at minimal cost. Even if all three progressive winners easily win in November — the expected outcome in their safely Democratic districts — the results supply opposition research and advertising material for competitive swing-district races far from New York City.[10][18]
Frames it asGoldman's concession speech was a direct warning: '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.'[20] The campaign produced at least one specific documented incident: a Brooklyn coffee shop publicly labeled Goldman a 'genocide enabler' and wrote that his money was probably 'coming from AIPAC anyways' — a comment Goldman's allies argued linked his Jewish identity to his donor associations.[25] Even Brad Lander — Goldman's opponent and the race's progressive winner — called some of the campaign-trail rhetoric directed at Goldman 'over-the-top toxic.'[24] Goldman and his allies argue that opposition to U.S. military aid to Israel is often packaged with language that crosses into antisemitism. Progressives counter that this confuses legitimate policy disagreement with bigotry against a people, and that Jewish candidates like Lander hold similar foreign policy views — which, they argue, shows the distinction. AIPAC and aligned donors framed their spending not just as defending an incumbent but as backing a clear foreign policy position: they argue the U.S.-Israel military partnership — which includes joint missile defense development, intelligence-sharing arrangements, and decades of cooperation aimed at limiting nuclear weapons programs in the Middle East — serves American strategic interests that go beyond any single Israeli government or policy decision.[5] Outside spending supporting Espaillat also came from beyond AIPAC: the Congressional Hispanic Caucus's own super PAC and the Latino Victory Fund each contributed substantial additional outside money. This reflected a coalition of institutional Democratic and Latino political organizations that saw Espaillat as their champion in Congress.[26] The stakes on the Espaillat side went beyond cultural representation: he was not only the first Dominican-American elected to Congress but also the first formerly undocumented immigrant to serve as a congressional lawmaker — a distinction that carried special weight in a district with a large immigrant community that his immigration legislation was specifically designed to protect. His departure also means the Congressional Hispanic Caucus must elect new leadership at a time when the Democratic caucus is already divided between its left and establishment wings.[12][26]
WhyGoldman and Espaillat are working to stay politically relevant after their defeats. AIPAC's institutional goal is to signal that challenging its preferred candidates comes at a cost — even though its spending failed to stop these losses. Keeping a pro-Israel consensus inside the Democratic coalition is a core part of AIPAC's mission.[5]
Impact on themBoth Goldman and Espaillat lose their seats. AIPAC suffered significant losses despite heavy spending, which may affect how it distributes resources in future primaries. Goldman's antisemitism charge has sparked a broader argument within the party — one the progressive wing will contest aggressively heading into November.[5][20]

Overall coverage is multi-perspective and relatively balanced. |
| Times of Israel | Israeli English-language media; foregrounds U.S.-Israel relations in American political coverage | 5 | Brad Lander, Jewish Mamdani ally and Israel critic, wins NYC Congressional primary | Leads with 'Israel critic' as Lander's primary identity, placing his foreign-policy stance ahead of his economic or housing platform. Covers his 'liberal Zionist' identity and 2023 departure from DSA in depth, foregrounding implications for U.S.-Israel relations over what NY-10 voters actually prioritized at the ballot box. |
| Al Jazeera English | Qatari state-funded; editorially sympathetic to Palestinian and Global South perspectives | 6 | Wins by Mamdani-backed candidates deal blow to pro-Israel camp in US | Leads with Gaza and Palestinian rights as the defining lens of the entire election, quoting Palestinian advocates calling it a 'political earthquake for Palestinian rights.' This is one accurate dimension of the story, but domestic economic issues — housing, healthcare, anti-establishment frustration — receive secondary treatment that doesn't reflect how many winning voters described their own motivations. |
| The Intercept | U.S. left; adversarial digital news outlet co-founded by Glenn Greenwald, Jeremy Scahill, and Laura Poitras | 6 | Socialists Are Setting the Agenda in New York City | The phrase 'setting the agenda' goes well beyond what the results demonstrated — three primary wins, not policy enactment. The framing is aspirational and celebratory, with minimal space given to establishment Democratic concerns, pro-Israel perspectives, or the general-election implications of the results. |
| Fox News | U.S. right | 7 | 'Party of Zohran': Mamdani emerges as Democratic kingmaker after socialist allies sweep NYC primaries; 'Winners and Losers Emerge After Socialist Earthquake Rocks NYC Primaries' | Consistent use of 'socialist' as a pejorative rather than a neutral descriptor; 'earthquake' implies crisis and disorder. The story is framed almost entirely around Republican political opportunity rather than what voters chose and why — treating the results as a weapon, not a news event. |
| Washington Times | U.S. right-conservative; historically associated with the Unification Church; consistent right-of-center editorial line | 8 | 'We have a new party': Mamdani's New York primary wins propel the Democratic Party toward socialism | Uses an activist's celebratory quote as the headline, implying the entire Democratic Party has already transformed — an extrapolation far beyond three safe-district urban primary wins. 'Propel toward socialism' is an editorial verdict dressed up as a factual description. |
