Dearborn voters must replace longtime Mayor Jack O’Reilly Jr., who has been largely missing from the public eye since last year before COVID-19 hit the state, citing undisclosed health issues. Residents head to the polls for a mayoral primary on Aug. 3. More than a half-dozen candidates are vying for the city’s top job. But whoever becomes the city’s new leader will face an old problem. During the past few weeks, many Dearborn residents on the east side and south end of the city have been emptying water and sewage from their basements because of heavy rains and flooding. Mayoral candidates made flooding a campaign issue by sending out flyers, posting Facebook videos, some even calling for independent investigations into what happened.
