“As the Constitution clearly declares, all state acts - and that includes “Ordinances of Secession” - are subject to Federal review.”
Nonsense, you’ve tried that argument before, and it’s still as ridiculous as ever. To interpret the Constitution that way eviscerates the right to self-governance, and that is a right which pre-exists and trumps even the Constitution. The Constitution depends on that right, without it, the Constitution is illegitimate, so your argument is self-defeating.
Were it ridiculous, you could answer it without handwaving.
The Supremacy Clause is pretty straightforward.
It doesn't derogate at all from self-governance, because the Federal government which reviews state acts is elected by the people themselves.
