Brad Lander, the former New York City comptroller and ally of Mayor Zohran Mamdani, has defeated U.S. Rep. Dan Goldman in their Democratic primary.
Lander, who had the endorsement of both Mamdani and U.S. Sen. Bernie Sanders of Vermont, beat the two-term incumbent on Tuesday. Goldman has represented New York’s lower Manhattan and Brooklyn brownstone district since first winning election in 2022.
Lander's victory puts him in strong position in the heavily Democratic 10th District en route to the November general election. He’ll face Republican Jennifer Moore, who was unopposed Tuesday.
Lander was acquitted earlier this month on charges related to a protest inside a building housing an immigration court and has pledged to push back against President Donald Trump’s administration.
Mamdani and his slate are promising to push the Democratic Party further left on key issues, the war in Gaza chief among them, even as establishment Democrats in Washington worry that their policies could alienate swing voters in midterm elections across the country this fall.
Espaillat, who chairs the Congressional Hispanic Caucus, faces another Mamdani pick, Darializa Avila Chevalier, a democratic socialist who once helped organize pro-Palestinian protests at Columbia University. Mamdani is also backing his democratic socialist ally, state Assembly Member Claire Valdez, who along with the rest of the mayor's candidates has vowed to abolish U.S. Immigration and Customs Enforcement.
“It’s not just a question of electing more Democrats. It’s a question of electing better Democrats, ” Mamdani said Tuesday. “When I look at these candidacies, I see in them a willingness to also put working people back at the heart of our politics.”
In Washington, House Democratic Leader Hakeem Jeffries downplayed the influence of the Mamdani-backed candidates should they prevail Tuesday, which would make them the overwhelming favorites to win congressional seats in November given New York City's strong Democratic makeup.
“We have agreed to strongly disagree,” Jeffries said of Mamdani on Capitol Hill. “There are 215 members of the House Democratic caucus. A handful of primaries that go in one direction or the other, in a given state or two, aren’t going to reshape who we are as House Democrats.”

Meanwhile, Democrat Jack Schlossberg, the 33-year-old grandson of former President John F. Kennedy, is hoping to write his own chapter in Camelot lore as he competes in a crowded field for a seat being vacated by retiring U.S. Rep. Jerry Nadler. Mamdani has made no endorsement in that race.
The Kennedy scion is running in one of the country's wealthiest congressional districts — covering much of the center of Manhattan — but faces questions about his lack of work experience against more seasoned opponents.
The field includes state Assembly members Micah Lasher, a longtime government hand backed by Democratic leaders, and Alex Bores, whose proposals to regulate artificial intelligence have triggered tech industry blowback. Also running is George Conway, who helped start the anti-Trump group, The Lincoln Project, and has centered his candidacy on impeaching the president.

Mamdani's insurgents
Mamdani, whose first six months in office have drawn praise from establishment Democrats and even President Donald Trump, has made a big push to promote three congressional candidates who are challenging Democrats supported by the party's leadership.
Two of Mamdani's congressional slate identify as democratic socialists, while Lander has often aligned himself with the movement. All three have repeatedly promised to “abolish ICE,” condemned the “genocide” in Israel and vowed to “tax the rich” if elected.
Mamdani's most polarizing pick is Avila Chevalier, 32, in her race against Espaillat, 71, who was the first Dominican American elected to Congress and represents a district in upper Manhattan and the Bronx.
Avila Chevalier has not held political office and casts herself as an outsider. Around an hour before polls closed, she was standing on a street corner in Harlem with controversial streamer Hasan Piker, chatting with voters in a final Election Day push.
On the next corner, a small truck displayed an ad attacking Avila Chevalier, highlighting a disparaging remark she made on social media about former Vice President Kamala Harris. Avila Chevalier had previously apologized for the post.
Espaillat’s allies have called Avila Chevalier unfit for office, pointing out a history of inflammatory and profane social media posts when she was in her 20s.
In East Harlem, 47-year-old voter Sara Hyler said she flip-flopped several times between Avila Chevalier and Espaillat in the lead up to Election Day, but eventually cast her ballot for Avila Chevalier after learning about AIPAC’s heavy support for the incumbent.
“It was the breaking point, my last straw,” she said of AIPAC’s donations to Espaillat.
Hyler said it was important to elect a new crop of progressive democrats who aren’t beholden to AIPAC and the Israeli government. “As much as I support Israel, I don’t think we should be paying for them,” Hyler said.
Lander, a fixture of the city's progressive Democrats, got the mayor's endorsement in a race against Goldman, a progressive former federal prosecutor who served as lead counsel for Trump’s first impeachment.
The war in Gaza has been a dividing line between the two candidates, both of whom are Jewish. Lander assailed Goldman for not being tough enough on Israel over its military action against Palestinians. Goldman has consistently criticized Israel's government and condemned settler violence but has stopped short of describing the conflict as a genocide, which Lander has done.
Still, Goldman amped up his criticism of Israel's war posture in response to Landers' barbs and shifting voter sentiments, all while seeking to keep his campaign focused on the high cost of living and such issues as opposing Trump's agenda.
Mamdani has also backed Valdez over Brooklyn Borough President Antonio Reynoso, in the race to succeed retiring U.S. Rep. Nydia Velazquez in a district covering parts of Brooklyn and Queens. Reynoso was Velazquez's handpicked successor, but failed to earn the mayor's backing.
Yvette Sanchez, a 30-year-old preschool teacher who voted for Espaillat, said she was put off by Mamdani's attempts to unseat the incumbent in her district and stifle Velazquez’s preferred successor, arguing that the established candidates are supported by Black and Latino communities.
“Do you just think you can insert anyone you want or do you actually want to listen to us?” Sanchez, who supported Mamdani last year, said of the mayor.

A Trump-influenced race in upstate New York
In northern New York state, a Trump acolyte with no previous political experience is facing a conservative state lawmaker in the Republican primary for a seat soon to be vacated by U.S. Rep. Elise Stefanik.
Anthony Constantino, head of the custom sticker company Sticker Mule, showcased his enthusiasm for the president by putting a massive “Vote For Trump” sign atop one of his company buildings. He also released a hip-hop album titled “Thank You President Trump," and commissioned a statue of Trump and gave it to the president in Florida. Trump has endorsed him.
Constantino's opponent, conservative state Assembly Member Robert Smullen, has strong support from local Republicans and has argued that Constantino's antics, which include regular bashing of the state GOP, make him unfit to serve in the House.
