Mayce Torres, a two-time aldermanic candidate, who was running in the Democratic primary, switched over to the Republican primary. Elena Tej Grewel, who had previously formed an exploratory committee for a prospective run, announced that she would not be running. Before DuBois-Walton's withdrawal, it had been anticipated the primary contest between Ellicker and her would have been competitive.
