During Virginia's ratification convention
John Taylor of Caroline - Didn't stutter:
“In the creation of the federal government, the states exercised the highest act of sovereignty, and they may, if they please, repeat the proof of their sovereignty, by its annihilation. But the union possesses no innate sovereignty, like the states; it was not self-constituted; it is conventional, and of course subordinate to the sovereignties by which it was formed.
The sovereignties which imposed the limitations upon the federal government, far from supposing that they perished by the exercise of a part of their faculties, were vindicated, by reserving powers in which their deputy, the federal government, could not participate; and the usual right of sovereigns to alter or revoke its commissions. “
If it is indeed a contract, the SOuthern States which border with Mexico may have a case against the union for breach of contract. “...provide for the common defense” is a sham along our porous southern border.
