New York City election officials thrust the race for the next mayor into turmoil Tuesday after erroneously counting test ballots alongside election night results, producing about 135,000 “dummy ballots” that skewed results of the city’s first major test of a new ranked-choice voting system. The major blunder forced the Board of Elections to retract preliminary results it had posted hours earlier. The board promised to republish corrected results Wednesday that will show whether Brooklyn Borough President Eric Adams will maintain his lead over former Sanitation Commissioner Kathryn Garcia and civil rights lawyer Maya Wiley. Practically, the results released Tuesday had little bearing on determining the final winner of the race, which won’t be certified until 125,000 absentee votes are counted beginning next week. This week’s results are meant to show only who would have won the election if absentee ballots weren’t included, an incremental data release intended to provide voters with at least some transparency into the process. But the debacle marks an inauspicious start for New York’s new system of ranked-choice voting, which asks primary voters to list their top five candidates in order of preference instead of picking just one.
