New York, New York - Zohran Mamdani's Democratic mayoral primary win has been met with widespread enthusiasm as the dawn of a new day for New York City.

"Congratulations to Zohran Mamdani and his thousands of grassroots supporters for their extraordinary campaign. You took on the political, economic and media Establishment – and you beat them. Now it's on to victory in the general election," said Senator Bernie Sanders, who had endorsed the 33-year-old state assemblymember.

Mamdani won the primary to lead the nation's largest city in a race he described as a referendum on the future of the Democratic Party. His platform centered on making the city affordable through rent freezes, free buses, no-cost childcare, and more.

The democratic socialist handily defeated disgraced former Governor Andrew Cuomo, long seen as the frontrunner despite his resignation from office in 2021 after multiple scandals. The 67-year-old, whose mayoral campaign boasted a record $25-million war chest, was accused of covering up Covid-19 deaths in nursing homes and of sexually assaulting 11 women.

"The working class is done with business as usual. We were proud to be the first union to endorse Zohran because it’s time for a political movement that puts the working class first," posted the United Auto Workers. "Our members spoke out and turned out in a big way – and we’re just getting started."

Representative Alexandria Ocasio-Cortez, who also endorsed the primary winner, said: "Congratulations, Zohran K. Mamdani! Your dedication to an affordable, welcoming, and safe New York City where working families can have a shot has inspired people across the city."

"Billionaires and lobbyists poured millions against you and our public finance system. And you won," she added.

Mamdani's Tuesday night victory also received support from fellow New York politicians.

New York City Comptroller Brad Lander, who came in third place in the mayoral primary, wrote, "Hope and solidarity won tonight, and will win again in November. Congratulations, Zohran K. Mamdani."

Lander attended Mamdani's watch party to celebrate after the two cross-endorsed each other in a bid to keep Cuomo out of office.

Also present at the watch party was New York Attorney General Letitia James, who hailed Mamdani's campaign as "fueled by the power of the people – people yearning for change in this city."

New York Governor Kathy Hochul posted on X, "Today, voters made their voices heard, demanding a more affordable, more livable New York City. I hear them loud and clear."

"Zohran K. Mamdani built a formidable grassroots coalition, and I look forward to speaking with him in the days ahead about his ideas on how to ensure a safe, affordable, and livable New York City," the state's top executive added.

Democratic National Committee Chair Ken Martin wrote, "Congratulations to Zohran Mamdani on a big victory in the New York City Democratic mayoral primary, and to all of the Democrats across the ballot who prevailed tonight."

Mamdani is now headed for the general election on November 4, 2025. He will be up against Republican nominee Curtis Sliwa and independent incumbent Eric Adams – and possibly Cuomo again, running as an independent.
