The four wards Joyce won — the 13th, 19th and 23rd on the Southwest Side, and the 41st on the Northwest Side — cut significantly into a historic constituency of the Daley family. Had Joyce not been on the ballot, Daley possibly could have made up the difference of about 7,000 votes that separated him from Preckwinkle — and even the 14,400 votes that separated him from Lightfoot.
