“…..New York City joins 20 other cities around the country, as well as multiple states, that have already started using this method in various elections. Maine, notably, implemented ranked-choice voting for the first time in a federal election in 2018….
….Ranked-choice voting lets voters mark their first-choice candidate first, their second-choice candidate second, their third-choice candidate third, and so on. Each voter has only one vote but can indicate their backup choices: If one candidate has an outright majority of first-place rankings, that candidate wins, just like a traditional election.
But if no candidate has a majority in the first round, the candidate in last place is eliminated. Voters who had ranked that candidate first have their votes transferred to the candidate they ranked second. This process continues until a single candidate gathers a majority.
Advocates of ranked-choice voting argue that it has many benefits. Because candidates need broad-based support to win, they are forced to engage with a wide range of voters, including groups that do not always see outreach from political campaigns.
