Paul Vallas, the former CEO of Chicago Public Schools, will be on the ballot in the April 4 runoff for Chicago mayor.

Data from the city’s Board of Elections has not yet made it clear who among the eight other candidates, including Democratic Mayor Lori Lightfoot, might get the second spot in a race centered on the city’s crime.

Vallas won the endorsement of Chicago’s conservative Fraternal Order of Police and faced accusations from his rivals of being a Republican despite declaring himself a Democrat.

Vallas has also been a school administrator in New Orleans and Philadelphia, and unsuccessfully campaigned for Illinois governor in 2002. When he didn’t qualify for the Chicago mayoral runoff in 2019, he endorsed Lightfoot.
