Age: 70
Occupation: Treasurer of Cook County

Reelected in 2018 with 82 percent of the vote, Pappas cleaned up an office inherited from a corrupt predecessor. But she’s done more than right a listing ship. She’s responsible for Cook County’s debt disclosure ordinance, which requires all taxing bodies to state their finances on tax bills, and is currently backing a bill in Springfield that would give struggling property owners an extra four months to pay.
