Democratic nominee Zohran Mamdani holds a dominating lead over his opponents for the New York City mayoralty — this one, by 21 percentage points ahead of runner-up Andrew Cuomo, according to a new Marist College poll.

The poll finds that Mamdani’s lead is halved if incumbent Eric Adams were to drop out, instead of non-Mamdani voters splintering among Cuomo, the former governor; Republican nominee Curtis Sliwa, a talk-show host and founder of the Guardian Angels; and Adams.

In the four-way poll, taken of likely voters, Mamdani got 45%; Cuomo, 24%; Sliwa, 17%; Adams, 9%; and the rest were undecided.

The poll was conducted from Sept. 8 through Thursday, of 885 likely voters, with a margin of sampling error of +/- 4.1.

Cuomo, running as an independent, has sought a two-man race, and there is pressure for Adams and Sliwa to drop out so Cuomo can mount the strongest challenge to Mamdani.

Mamdani, a democratic socialist, stunned the political establishment by trouncing Cuomo in the Democratic primary earlier this summer.
