2013 New York City mayoral election

An election for the mayor of New York City occurred on November 5, 2013, along with elections for comptroller, public advocate, borough president, and members of the New York City Council. The incumbent mayor, Michael Bloomberg, a Republican-turned-Independent, was term-limited and thus unable to seek re-election to a fourth term in office. Primary elections were held on September 10, 2013. The Republican nominee was former Metropolitan Transportation Authority Chairman Joe Lhota. New York City Public Advocate Bill de Blasio was the Democratic nominee. De Blasio was elected mayor with 73 % of the vote, becoming the first Democrat to win a mayoral election in the city since 1989. Democrats flipped back the boroughs of Manhattan and Queens.
