Jackson’s brother, Jonathan Jackson, and his wife Sandi Jackson — who currently serves as an alderman representing a part of the district — also have been mentioned, though neither has commented on a possible run.
Serafin said the Jackson name could draw a strong base of voters to the polls. If roughly 135,000 to 200,000 voters turn out and the field is split between multiple candidates, that base could be enough, he said.
Among the other possibilities are Cook County Board President Toni Preckwinkle and state senator-elect Napoleon Harris, who played in the NFL and owns two pizza franchises. His campaign aide, Curtis Thompson, told The Chicago Sun-Times Harris was taking the holidays to think about it.
