Nobody's denying what Scalia said. No one ever has.
What you won't get any of the framers to say is that unilateral secession is allowed in U.S. law.
You can't seem to even find anyone who gainsaid Jay and Wilson's statements that I quote above. No one was denying the primacy of the federal government in the 1790's. No one did-- until Calhoun made up the ideas of nullificatiion and secession from whole cloth.
