Five candidates have submitted their petitions for the special election to fill the Fourth Ward aldermanic seat so far, less than 100 days shy of Election Day on February 28. Three challengers to incumbent interim Ald. Sophia King, who was appointed by Mayor Rahm Emanuel this past spring, lined up outside the door of the Chicago Board of Elections just before 9:00 a.m. Monday to turn in thousands of signatures gathered since August: Marcellus Moore Jr., Ebony Lucas, and Gregory Seal Livingston. One other, Jack Taylor, filed just after the morning rush. All noted their own independence and a perception that Ald. King, a mayoral appointee, is lacking it.
