Zohran Mamdani, the front-runner, and his rivals, Andrew M. Cuomo and Curtis Sliwa, are racing to turn out voters before Election Day on Tuesday. Polls are open Sunday from 9 a.m. to 5 p.m.
Zohran Mamdani holds a considerable lead in most polls, and wealthy supporters of Andrew M. Cuomo are giving him a late financial boost. More than 480,000 New Yorkers have voted early.
