Topic A -- certain state governors don't want to be mandated to do something they don't like that's gaining popular support, and so declare / pass laws that prevent localities from passing their own mandates (any current topic you can think of?)
Topic B -- same or other state governors don't want to have federally mandated rules on another topic, so go against the principle they just used for their own localities, and say that they cannot be mandated to follow something they disagree with.
Topic C -- yet another topic comes up where governors want everyone to follow a certain guideline and not deviate, and insist that every locality does follow top-down legislation, and get upset at other states that don't follow the rule.
Topic D -- "states should have the right to try their own solutions" and not be imposed upon by peanut-butter inappropriate federal solutions on things they disagree with.
Topic E -- "states should follow rules given from the federal government" on things they do agree with.
I'm sometimes exhausted by this patchwork. And principles that flap in the wind.
