The Mayor Mary Rules:
If she agreed with whatever you were trying to do in Madison, you like her.
If she didn't agree with whatever you were trying to do in Madison, you hate her.
If you are actually envious of Madison and the property values, low crime, and here pumping those facts, you hate her.
You may just hate her because your are friends with someone who said she was terrible.
She is a bit unusual in politics in that she does actually stand for something, hence the number of people who either love or hate her. All that said, she has kept Madison on a decent path and she would absolutely crack heads of people who she thought were doing "wrong" in the state. Those she liked would not get a second look. In other words, business as usual at the state level of politics...
ETA: I don't live in Madison the City.
