On Tuesday, Chicago voters elected Lori Lightfoot, its first African-American female mayor. Her opponent, Toni Preckwinkle, would have held that same distinction but was completely blown out. Lightfoot bested her by 2% in the first round, but positively routed her in this one, carrying the vast majority of the city’s precincts. Lightfoot won virtually every demographic, but was particularly strong in wealthy areas dominated with college-educated whites, like the Gold Coast. Some had assumed that Lightfoot, without machine backing and trailing Preckwinkle in overall fundraising, would still face a race, but polling released between the runoff and Tuesday had foretold the landslide win.
