You invented your "fact". Sourceless, citeless, quoteless. Always.
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, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.
Of course, I already know that the Constitution itself isn't enough of a cite for you, my little sock puppet troll.
Squeek for me again Roscoe.
