Contrary to some popular belief, the Constitution is NOT a "living breathing document" in either its ability to be changed or in interpretation.
It was meant to be very difficult to change for a reason. It is a legal document that limits government not limits citizens.
I cannot imagine the tyranny that would exist with the current regime if that wonderful document was not in existence or was easily changed or discarded. Even at that, the current regime has trampled on it like it is trash to them.
