A supremancy clause allows the National Government to out do smaller
levels of Government, in doing so can prevent unfair policies and a lack
of justice in that form of Government that's all wrong
Simply StatedThe Supremacy Clause makes invalid any law passed by a
State or local government that is in conflict with a federal law. In
other words, federal law is "supreme." Though that concept seems
simple, it's application is not. So don't start throwing around the
"supremacy clause" unless you understand how the courts apply it. The importance of the Supremacy clause is that it establishes that the
Constitution and Federal Law are the absolute law of last resort in the
United States. By that, it means that the Constitution or Federal Law
will win in any conflict between it and any state or local law. Thus,
all states are bound to the limits placed on them by the Constitution
and federal law. In practice, here's what it means: no state or
locality can pass a law which prohibits something expressly allowed by
the Constitution or Federal law, nor may a state or locality allow
something expressly forbidden by the Constitution or Federal law.
