Alex Bores, George Conway, Laura Dunn, Micah Lasher, Jack Schlossberg, Nina Schwalbe, Chris Diep, Patrick Timmins and Micah Bergdale 3.
No. As of May 2026, Mamdani has not endorsed any candidate. Mamdani narrowly lost NY-12 in the 2025 mayoral primary to Andrew Cuomo, who took 37% in the first round to Mamdani's 33% 35.
Alex Bores represents the 73rd Assembly District (Upper East Side), elected to the Assembly in 2022. He worked as a software engineer and manager at Palantir from 2014 to 2019 and holds a bachelor's degree from Cornell and a master's in computer science from Georgia Tech. Bores says he left Palantir in 2019 over the company's renewal of its ICE contract. A February 2026 Bloomberg Law report alleged he also received a formal warning over sexually explicit comments to a colleague shortly before resigning; Bores's campaign disputes that the warning was the reason for his departure 1615.
Micah Lasher represents an Upper West Side Assembly district, elected in 2024. He previously served as director of policy for Gov. Kathy Hochul, director of state legislative affairs for Mayor Michael Bloomberg, and as a staffer to Rep. Nadler 13.
Jack Schlossberg, 33, is a writer and social-media personality who has previously worked at Rakuten and the U.S. Department of State. He is the grandson of President John F. Kennedy and the son of Caroline Kennedy 17.
George Conway, 62, is an attorney and prominent television critic of President Trump, and the ex-husband of Kellyanne Conway. He registered as a Democrat in 2025 before launching his congressional campaign 17.

Conway is one of the most prominent television and print critics of President Trump and was a co-founder of the Lincoln Project and Society for the Rule of Law. He has built his campaign around legal and constitutional opposition to the second Trump administration 37.
Lasher has said he wants to bring an aggressive approach to fighting the Trump administration to Congress and has emphasized his policy and legislative experience as preparation for that fight 4.
Yes. Bores has said publicly that he called to abolish ICE before he ran for Congress, repeated that position during the primary, and has called Trump and Homeland Security Secretary Kristi Noem responsible for current enforcement practices 8.
NY-12 has become an early battleground over federal AI policy, in part because Bores is the lead Assembly sponsor of New York's RAISE Act and has been targeted by an AI-industry super PAC and supported by a pro-regulation super PAC 91011.
The Responsible AI Safety and Education (RAISE) Act, signed into law by Gov. Hochul in December 2025, requires the largest AI developers to publish safety and security protocols for severe risks, such as helping create bioweapons or carrying out automated criminal activity, disclose major safety incidents, and allows the New York attorney general to seek civil penalties for violations 910.
Bores released an eight-point national AI plan in February 2026 that includes a federal version of the RAISE Act, independent safety testing of frontier AI models, mandatory reporting of AI-related job losses, an AI dividend funded by productivity gains, and tying data-center permitting to renewable-energy use 11.
Leading the Future, backed by Andreessen Horowitz, Palantir co-founder Joe Lonsdale, Perplexity, and other AI investors, has spent against Bores. Jobs and Democracy PAC, a sister entity supported by an Anthropic donation, has spent in favor of Bores. As of May 2026, the anti-Bores PAC had spent roughly $2.4 million and the pro-Bores PAC roughly $1.2 million 1012.
Diep has run on a platform that centers on AI's impact on workers and jobs 3. Other leading candidates have addressed AI policy in forums but have not made it the centerpiece of their campaigns 38.
NY-12 contains the largest Jewish population of any U.S. congressional district, and candidates have addressed Israel policy in district forums and synagogue events. Coverage describes broad alignment among the leading candidates on support for Israel's security, combined with criticism of Netanyahu, though the candidates differ on tone and specifics 713.
Lasher has said he supports a two-state outcome and continued U.S. security cooperation with Israel, and has been endorsed by Mayor Bloomberg, a longtime supporter of pro-Israel policy positions 34.
Bores has supported continued U.S. security cooperation with Israel while criticizing the Netanyahu government's conduct of the war in Gaza and supporting humanitarian access 8.

Schlossberg has said he supports a two-state solution and has emphasized humanitarian-aid access in Gaza 7.
Lasher's campaign emphasizes his role in passing what his campaign describes as landmark New York laws to strengthen gun control during his time as a policy aide and legislator 14.

Dunn founded SurvJustice, which advocates for survivors of sexual violence and reform of how the legal system handles sexual assault and harassment cases. Her congressional platform centers on civil rights and survivor-protection policy 38.
All leading candidates have stated support for federal codification of Roe v. Wade and federal abortion protections 38.
Schwalbe, a public-health researcher and advocate, has built her campaign around a science-and-health-policy lane, focused on pandemic preparedness, drug pricing, and federal public-health infrastructure 38.

Former Rep. Carolyn Maloney endorsed Bores. LGBTQ+ activist Matthew Shurka endorsed Bores after dropping his own bid 314.
Former House Speaker Nancy Pelosi endorsed Schlossberg 3.
Conway has not consolidated major institutional endorsements and is running on his national TV-pundit profile and high direct-fundraising totals 37.
Through Q1 2026, Conway raised roughly $3 million; Bores, Lasher, and Schlossberg each raised approximately $2 million 7. Bores had received more than $2.2 million by the end of 2025, and Lasher had raised roughly $1.4 million 13.
The Bloomberg-backed super PAC has spent in the multiple-millions on Lasher's behalf. The Leading the Future PAC has spent against Bores. Jobs and Democracy PAC has spent on Bores. As of mid-May 2026, those totals were roughly $4.3 million for Lasher, $2.4 million against Bores, and $1.2 million for Bores 312.
Three early polls (a Conway-commissioned GQR poll, a Leading the Future Schoen Cooperman poll, and a Public Policy Polling poll for Dream NYC) showed Schlossberg leading on initial name recognition. A March 2026 Bores-campaign poll showed Schlossberg at 22%, Bores at 19%, Lasher at 14%, and Conway at 10%, with one-third of voters undecided 31314.
Political insiders generally describe the race as a Lasher-versus-Bores contest, often framed as an Upper West Side versus Upper East Side fight, with Schlossberg as a name-recognition wild card and Conway as a fundraising threat 357.
