Brandon Johnson elected as Chicago's new mayor.

Brandon Johnson, a former teachers' union organizer and county commissioner, has been elected as the new mayor of Chicago. Johnson's victory signals a shift to the left from the already progressive politics of Mayor Lori Lightfoot's administration. He faces the challenge of bringing together a divided city and tackling persistent crime, which was a major issue in the campaign. Johnson's campaign was supported by the Chicago Teachers Union, while his moderate rival Paul Vallas was endorsed by the Chicago Fraternal Order of Police. Johnson will take office facing a City Council that's already more independent than the one Lightfoot has worked with for the past four years.
