Chicago Mayor Lori Lightfoot has lost her re-election bid and conceded defeat, becoming Chicago’s first one-term mayor in 40 years.

Lightfoot conceded Chicago’s mayoral race Tuesday evening, shortly before 9 p.m., after 89% of the precincts showed the mayor headed for a third-place finish with 16.4% of the vote.

“Obviously, we didn’t win the election. But I stand here with my head held high and my heart full of thanks,” Lightfoot told supporters.

Lightfoot, the first Black woman and the first openly gay person to serve as Chicago’s mayor, came in third behind former Chicago Public Schools chief executive officer Paul Vallas who had 35.2% of the vote and Cook County Commissioner and Chicago Teachers Union organizer Brandon Johnson with 20.25%, as of Tuesday night.
