All of that happened in very low income neighborhoods that are not significantly impacted by the LEZ and outside the M30. In fact, she even got a small but meaningful vote boost from LEZ residents.
EDIT: Article says “City centre residents are happy with the LEZ “
Notice that the politician in question is not a candidate for mayor of the city, it's the candidate governor of the whole region around the city.
Are you speaking specifically about residents from Madrid center or just generic city center residents?
thousands of people are dying in big cities from pollution and the local government should take unpopular actions to tackle climate change. of course nobody wants to be affected in any way by climate change, they want other people to do it.
How is that a "weird definition of democracy"? That's literally what democracy means!
Yes, if a majority of people want policies which result in them dying by the thousands from pollution, then in a democratic system, that's what you have to give them. If the politicians do something highly unpopular, even though it's for the good of the society, they get voted out (assuming there's competing politicians who promise to give the people what they want). That's how democracy works. This is why democratic systems don't work very well when the populace is uneducated and stupid.
