2001 New York City mayoral election
Updated: Wikipedia source
The 2001 New York City mayoral election was held on November 6, 2001. Incumbent Republican mayor Rudy Giuliani could not run again due to term limits. As Democrats outnumbered Republicans by a five-to-one margin in the city, it was widely believed that a Democrat would succeed him in City Hall. Businessman Michael Bloomberg, a lifelong Democrat, changed his party affiliation to run as a Republican. Mark Green narrowly defeated Fernando Ferrer in the Democratic primary, surviving a contest that divided the party and consumed the vast majority of the Green campaign's financial resources. After a campaign largely overshadowed by the 9/11 terrorist attacks, Bloomberg won the general election with 50.3% of the vote to Green's 47.9%. Democrats flipped the boroughs of Manhattan and Brooklyn from the previous election. This is one of two mayoral elections where the winning candidate carried a minority of the boroughs, the other being the 1969 election.
