== Should this have a citation? == 

 "Additionally, in the 20th century, the Supreme Court held that the Due Process Clause of the Fourteenth Amendment applies the limitations of the First Amendment to each state, including any local government within a state."  This sentence in the intro is uncited, and I can't seem to find anything in the article on the 14th amendment or due process on it. Perhaps it should have a citation for whatever decision it's referring to? I'd certainly find it helpful, at least )
