Ald. Michael Scott (24) will chair the selection committee tasked with appointing a replacement for his mentor, Cook County Comm. Robert Steele, who passed away Monday morning. The district that he and his mother, former Cook County Board President and Commissioner Bobbie Steele, represented for decades spans both the city’s South and West Sides and covers 19 wards. Only two committeemen hold more than 10% of the weighted vote, which sources speculate could lead to a fraught nomination process.
