Democrat Bill de Blasio defeated Republican Joe Lhota in Tuesday's election for New York City mayor.
De Blasio, currently serving as the city's public advocate, will succeed outgoing Mayor Michael Bloomberg, who is completing his third and final term in office.
Since winning the Democratic primary in September, de Blasio has held a wide lead over his Republican rival.
Reuters reported earlier Tuesday:
Democrats have been locked out of City Hall for two decades despite holding a 6-to-1 registration advantage over Republicans.
Bloomberg, founder of the eponymous financial news and information company that competes with Thomson Reuters, spent more than $260 million of his own money on his three elections.

De Blasio rose in the polls while lamenting that the contrast between the "haves" and "have nots" has grown increasingly stark.
He has especially criticized the controversial police tactic of stop-and-frisk, which critics say unfairly targets poor blacks and Latinos. Bloomberg has called the approach central to the city's anti-crime fight, while de Blasio has blasted it as destructive to police and community relations.
