In another thread about Christine O'donnell, Crabby kept informing us that the US Constitution states "separation of Church and State". If that were so, then why did several states have official religions?
It wasn't until the late 1800's did the last State end having an official religion.
Its interesting what some of the State Constitutions had to say.
Selective incorporation is the process by which the Supreme Court applies select provisions of the Bill of Rights and relevant case law to the States in order to fulfill the Due Process Clause of the Fourteenth Amendment.
