This is the "laboratory" idea spoken about by so many people, and now you hear the current candidates repeating it. Look, if Massachusetts wants to inflict some ridiculous law, that is the right of the people of that state....same for Florida or Rhode Island or Hawaii.
This is what gives Americans the FREEDOM to move around and choose where they live.
The "people" didn't decide. Government TOLD them and THAT is the point. Government can be over-reaching whether federal, state or local. It is socialism at ANY level, NOT freedom.
