De Blasio sails to second term as NYC mayor

New York City's mayor, Democrat Bill de Blasio, was elected to a second term Tuesday, beating Republican opponent Nicole Malliotakis after leading her by over 40 points in recent polls.

Big-name Democrats Bernie Sanders and Elizabeth Warren campaigned and fundraised for De Blasio, but he was almost guaranteed to keep his seat in a city where Democrats outnumber Republicans nearly 7 to 1.
