Progressive Brandon Johnson wins Chicago mayoral election.

Former teacher and union organizer Brandon Johnson has been elected as the new mayor of Chicago, defeating former public schools executive Paul Vallas in a tight race. Johnson campaigned on expanding social programs and new taxes, focusing on mental health treatment, affordable housing, and jobs for youth instead of further investing in policing and incarceration. His win is a momentous victory for progressive organizations such as the teachers union. Johnson will succeed Lori Lightfoot as the city's mayor, becoming the highest office of any active teachers union member in recent history.
