While Mr. Adams’s lead was dispiriting to some on the left, New York’s progressives did hold out hope in some other key down-ballot races.
In Manhattan, the district attorney’s race was too close to call with Alvin Bragg, a progressive, holding a narrow lead over Tali Farhadian Weinstein. Ms. Weinstein, a more moderate Democrat, had injected more than $8 million of her own money into her campaign in the race’s final weeks, earning the ire of progressives for the spending and her ties to Wall Street.
In the city comptroller race to replace the termed out Mr. Stringer, Brad Lander, a progressive from Park Slope, Brooklyn, led Corey Johnson, the City Council speaker, by a similar margin as Mr. Adams led Ms. Wiley in the mayor’s race. Like Ms. Wiley, Mr. Lander had been endorsed by Ms. Ocasio-Cortez and Ms. Warren.
Jumaane Williams, the current New York City public advocate and an outspoken progressive, cruised through his primary and won roughly 70 percent of the vote.
In one of the marquee City Council races for the left, Tiffany Cabán, who previously ran for Queens district attorney, was leading by a wide margin with backing of the Democratic Socialists of America. Other progressive favorites were leading in council seats, including Sandy Nurse and Jennifer Gutierrez.
In Buffalo, New York’s second largest city, India Walton, a Democratic Socialist, was poised to upset the four-term incumbent Democrat, Byron Brown. Mr. Brown is a former New York Democratic Party state chairman and a close ally of Gov. Andrew M. Cuomo.
