Next Chicago Mayor Will Be a UChicago Graduate

I wonder if there has ever been a run-off election like this for a position of this magnitude. The two top vote-getters (a) combined got less than 12% of eligible voters and barely a third of the votes actually cast, and (b) seem to have been immediately adjacent to one another on the ideological/social spectrum of 14 candidates. Their positions are almost indistinguishable, although they are from different generations and have different resumes. It’s not at all clear to what extent either naturally inherits any other candidate’s supporters.
