I don't think Chicago is a good example of this, given who the two runoff candidates are: the proto-Republican (there is no serious Republican nominee for Chicago mayor, only the Republicaniest Democrat) and a neo-Defunder who is likely to win.

Chicago has much more to do with outgoing mayor Lightfoot's across-the-board negatives --- with her handling of the school system, with her COVID handling, and with her handling of the police department --- than it is a straightforward reaction to crime.
