Apparently, the board appointments are set up to "serve at the pleasure of the Mayor" or something like that, and Curry's team has interpreted that to mean that the mayor can change them out when he sees fit. He wants to fill the boards with folks he can work with to pursue his vision. However, it hasn't really been done before by previous mayors, and whether Curry intends it this way or not, without a doubt the moves look politically motivated, which takes away from the good work he's done with the staff and appointments so far. That said, the people he's been picking have for the most part been solid, so at least there's that. At any rate, it's in the Council's hands now, hopefully Curry learns from the experience.
