Updated: Wikipedia source
The 2005 New York City mayoral election occurred on November 8, 2005. Incumbent Republican mayor Michael Bloomberg soundly defeated former Bronx borough president Fernando Ferrer, the Democratic nominee. Several third-party candidates also ran for mayor. In July, mayoral candidates filed nominating petitions with the City Board of Elections. Bloomberg won four of the five boroughs, the exception being the Bronx. He flipped the boroughs of Manhattan and Brooklyn. To date, this is the last time a Republican was elected mayor of New York City, and the last time a Republican line carried Brooklyn. Bloomberg left the Republican Party in 2007 to register as an independent, but the Republican Party nominated him for reelection in 2009.
