Democratic Party officials will choose who fills his term until next year, as well as the statehouse seat of Lamont Robinson, who won a city council seat.
Chicagoans cast their ballots to choose Chicago's 57th mayor earlier this week as Brandon Johnson and Paul Vallas both campaigned on messages of change.
Johnson won 29 of 50 wards, including a clean sweep of majority African-American wards. He won six Hispanic majority wards to Vallas’ nine. Johnson sealed the deal along the progressive-minded north lakefront and the hipster Milwaukee Avenue corridor.
