adhere to the Constitution because it doesn't in many instances.

The US Constitution is the supreme law of the land. and any statute, to be valid must be in agreement. It is impossible for both the Constitution and a law violating it to be valid. "No one is bound to obey an unconstitutional law, and no courts are bound to enforce it."--American Jurisprudence, 2nd Edition
Clearly a federal law which is contrary to the Constitution is no law at all., it is null, void,invalid....it is the height of absurdity to claim a Supreme Court decision that manifestly violates the Constitution is the Supreme Law of the land."--William Jasper
The laws of Congress are restricted to a certain sphere & when they depart from this sphere they are no longer supreme or binding."---Alex Hamilton
