The Supremacy Clause gives supreme power to the feds.
The Militia Act of 1792 requires that U.S. law operate in all the states. The Judiciary Act of 1789 requires that civil controversies between the states be submitted to the SCOTUS.
So was secession a civil act, or a criminal act?

"Abraham Lincoln, 1838:
"This country, with its institutions, belongs to the people who inhabit it. Whenever they shall grow weary of the existing government, they can exercise their constitutional right of amending it, or their revolutionary right to dismember it or overthrow it."
Then you'll say the Supreme Court says that secession was illegal -
Abraham Lincoln, First Inaugural Address, March 4, 1861:
"... the candid citizen must confess that if the policy of the Government upon vital questions affecting the whole people is to be irrevocably fixed by decisions of the supreme Court, ... the people will have ceased to be their own rulers, having to that extent practically resigned their Government into the hands of that eminent tribunal."
Chief Justice Marlin T. Phelps, Arizona Supreme Court:
"Nothing was further from the minds of the Framers of the Constitution, than that the supreme Court should ever make the Supreme Law of the Land."
Senator Sam Ervin:
"... judicial verbicide is calculated to convert the Constitution into a worthless scrap of paper and to replace our government of laws with a judicial oligarchy."
Thomas Jefferson, 1820:
"You seem...to consider the judges as the ultimate arbiters of all constitutional questions; a very dangerous doctrine indeed, and one which would place us under the despotism of an oligarchy.... The Constitution has erected no such single tribunal."
Thomas Jefferson in a letter to William S. Smith in 1787. Taken from Jefferson, On Democracy 20, S. Padover ed., 1939: "And what country can preserve its liberties, if its rulers are not warned from time to time that this people preserve the spirit of resistance? Let them take arms .... The tree of liberty must be refreshed from time to time, with the blood of patriots and tyrants."
Paul Anderson (?? I think. _Not_ Poul):
"If the price I must pay for my freedom is to acknowledge that the government was granted the power to infringe on them, then I am not free."
