How to read this:
Ranked Choice Voting eliminates the last-place candidate each round, transferring their
ballots to each voter's next ranked choice still in the race.
Ballots in contest = voters who ranked at least one candidate here.
Active votes = ballots still assigned to a remaining candidate in a given round.
Exhausted ballots = ballots where all ranked choices have been eliminated.
Vote counts shown in each round reflect votes before that round's elimination.
Ties broken alphabetically by candidate ID (NYC BOE uses random draw; ties are rare at scale).

How Many Candidates Did Voters Choose to Rank?
NYC primary voters may rank up to 5 candidates in order of preference — but they are not required to.
This chart shows how many candidates each voter chose to rank (1 = ranked only their top choice; 5 = used all available rankings).
Voters who ranked only one candidate are more likely to exhaust — their ballot stops counting once that candidate is eliminated.
