Ranked-choice voting could once again decide New York City’s mayoral primary, four years after the process was slow and marred by a major tabulation error.

Registered voters in the city can cast ballots in the Democratic primary for mayor and other races starting on Saturday, which is also the deadline for voter registration.

Early voting began on a rainy Saturday as New Yorkers cast their votes in a crowded Democratic mayoral primary largely shaped by concerns about affordability, housing, public safety and the rise in antisemitism.
