Fran Spielman interviews Ald. Marty Quinn of Chicago’s 13th Ward, who announces he will not seek re-election after four terms and 15 years on the City Council, citing the demands and unpredictability of ward service, sacrifices to family life, and readiness for new challenges with no job lined up. Quinn reflects on the council’s evolution from a seniority- and ward-focused body under Rahm Emanuel to a more legislative, independent, and coalition-driven council under Lightfoot and Johnson, including opposition to Johnson’s head tax and last year’s budget coalition.
