The Windy City decided on its new mayor Tuesday after a tight race between two blues, with a progressive, Bernie Sanders-endorsed Democrat taking the keys to the Chicago mayor's office.

Progressive Cook County Commissioner Brandon Johnson defeated his moderate opponent, former Chicago Public Schools CEO Paul Vallas, to take the Chicago mayor’s race, replacing outgoing Mayor Lori Lightfoot, who came in third before the runoff.

Vallas garnered the support of the Chicago police union and major business groups while Johnson got the backing of Chicago's teacher's union.
