The revenge of the ratepayers
At my Patreon, I have done a table showing the 71 mayoral election results, and what the rates increases for each council was (both last year, and last three years).
Of the councils with the ten highest rates increases, only one Mayor was re-elected. This is a good thing. It shows the power of ratepayers who get sick of being ATMs. Hopefully it will also act as an incentive for the new Mayors and Councils to restrain non-core spending.
