Just 20 percent of New York City voters approved of Mayor Eric Adams’s job performance in a poll released Wednesday, and more than half said he should resign, demonstrating that he faces a daunting path to re-election this year.

Mr. Adams’s approval rating in the poll, conducted by Quinnipiac University, was the lowest for any New York City mayor since the university began surveying the city’s registered voters nearly 30 years ago. It represented a significant drop from the previous low of 28 percent that Mr. Adams, a Democrat, received in the poll in December 2023.

The poll found broad dissatisfaction with the mayor, including from members of his own party. Sixty-seven percent of registered voters, and 78 percent of registered Democrats, disapproved of his job performance, and 56 percent of voters and 72 percent of Democrats said he should resign. Only 18 percent of voters said the mayor, who faces federal corruption charges, was honest and trustworthy.

And the poll found that 72 percent of voters were either very dissatisfied or somewhat dissatisfied with the direction of the city, traditionally an indicator of unhappiness with the incumbent mayor.

Mr. Adams’s poll numbers were low even before he was indicted last year on five counts. Since then, his situation has grown even more complicated.

The Justice Department moved in recent weeks to dismiss the corruption charges against Mr. Adams so that he could assist with the Trump administration’s immigration crackdown. The top federal prosecutor in Manhattan resigned rather than comply, asserting that Mr. Adams had agreed to a quid pro quo with the Justice Department.
