The winner of the Democratic primary will face Adams, Republican candidate Curtis Sliwa, and independent candidate Jim Walden come November, but is likely to become the next leader of the city, which has selected a Democrat in the past three mayoral elections. Polls are open in the city until 9 p.m.

The Democratic primary for comptroller is for an open seat, with the incumbent, Brad Lander, running for mayor. The winner of the crowded race will become the heavy favorite to preside in November, and be charged with overseeing the city’s pension funds and auditing its agencies.

Brad Lander, New York City’s Comptroller and Democratic mayoral candidate, was detained by masked Immigration and Customs Enforcement agents. Lander was arrested as he was escorting a migrant out of an immigration courtroom in Manhattan.
