NEW YORK — New York City Mayor Eric Adams said Sunday he is ending his reelection campaign, a move that virtually ensures he will lose in November and seals his fate as the city’s first one-term mayor since David Dinkins.

Adams’ decision to end his campaign comes after anemic polling, the loss of millions of dollars in public matching funds and record-low approval ratings driven partly by the indelible mark of President Donald Trump on Adams’ defunct criminal bribery case.

Moderate Democrats — and even Trump himself — have long hoped to winnow down the general election field to give Andrew Cuomo, who is running as an independent, a better chance of catching up to frontrunner Zohran Mamdani, the democratic socialist who won an upset victory in the June Democratic primary.
