In the mind of New York's mayor, high approval ratings for politicians mean they aren't doing a good job.
As he explained to The Atlantic:
If I finish my term in office … and have high approval ratings, then I wasted my last years in office. That high approval rating means you don’t upset anybody. High approval rating means you’re skiing down the slope and you never fall. Well, you’re skiing the baby slope, for goodness’ sakes. Go to a steeper slope. You always want to press, and you want to tackle the issues that are unpopular, that nobody else will go after.
...like banning large sodas?
