CHICAGO — Chicago Mayor Lori Lightfoot lost her bid for re-election Tuesday, ending her historic run as the city’s first Black woman and first openly gay person to serve in the position. Lightfoot is the first incumbent elected Chicago mayor to lose re-election since 1983, when Jane Byrne, the city's first female mayor, lost her primary. She faced stiff competition, particularly from Johnson, who had the backing and organizational benefits of the powerful Chicago Teachers Union, as well as Willie Wilson, a Black entrepreneur who had been polling ahead of Johnson
