“Most of these bills are not as aggressive as Georgia’s, but they all undermine localities’ ability to self-rule. In this way, Illinois State University political scientist Lori Riverstone-Newell told FiveThirtyEight, they’re part of an increasing trend of states preempting local government in order to retain power for themselves: Conservative legislatures, in particular, have passed several laws in recent years that limit the types of laws municipalities can pass, including sanctuary-city protections, anti-LGBT discrimination ordinances and minimum-wage increases (especially in the South). These laws can often have what Riverstone-Newell calls a “chilling effect,” where the mere threat of having their power taken away makes local officials afraid to govern as they see fit.”
