QUOTE : The principle of nationalism was not merely implied in the Constitution; it was set forth explicitly in what is known as the Supremacy clause, Article VI of the Constitution, which says: <br /><br /> This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made under the Authority of the United States, shall be the supreme Law of the land; and the Judges in every State shall be bound thereby, anything in the Constitution and Laws of any State to the contrary notwithstanding. <br /><br />The supremacy Clause is quite clear: States cannot pass laws against the laws of the national government. Even state constitutions are limited not just by the U.S. Constitution, but also by laws passed by congress. The delegates saw that it had to be this way, for the national government would be of no use at all if the states could pass laws contrary to national ones.
