Chicago chooses between progressive, moderate for mayor

Chicago voters are choosing a new mayor to lead the heavily Democratic city. Tuesday's runoff pits former Chicago schools CEO Paul Vallas against progressive Brandon Johnson. Vallas is a moderate Democrat endorsed by Chicago’s police union and major business groups. Johnson is a former teacher and union organizer backed by the Chicago Teachers Union. Both men finished ahead of current Mayor Lori Lightfoot in a February election, making her the first incumbent in 40 years to seek reelection in the city and lose. The top two vote-getters in the all-Democrat but officially nonpartisan race moved to the Tuesday runoff because no candidate received over 50% of the vote.
