“Ranked-choice” voting, or “RCV” comes to the Big Apple starting in June 2021, she said. Right now, the candidate who wins the biggest percentage of votes for city office wins, even if it’s less than 50%. But under RCV, voters will rank their top five candidates from first to last for each seat. If no one wins a majority on the first go, then the last-place candidate will be eliminated and the votes reallocated.
