The Federal Supremacy Clause is the formal text by which Federal Law generally trumps state law if the two are in explicit direct conflict as quoted below from the U.S. Constitution:
Article VI, Clause 2: 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.
However, does this specific clause also preempt portions of State Constitutions? That is, if the Federal Government passes a law that is in direct conflict with a portion of a State's Constitution, does that portion of the State's Constitution become preempted in the same fashion as a conflicting state law would?
