Brad Lander wins Democratic primary for NYC comptroller A voter scans a completed ballot during the New York City mayoral primary election. New York City Council member Brad Lander won the Democratic primary for New York City's comptroller, according to an unofficial vote count posted Tuesday by the city's board of elections. Mr. Lander was leading Corey Johnson, the city council president, by 51.9% to 48.1%. Mr. Johnson conceded. Although voting took place June 22, the delayed posting of results was due to New York City using a ranked-choice voting system, the counting of a large amount of absentee ballots and the board of elections mistakenly counting 135,000 sample ballots in the tally for citywide offices, including those of mayor and comptroller.
