There was NO "conditional ratification" allowed or accepted. That is just another bogus DS delusion.
I agree. They stated that their ratification was dependent upon their ratifying statement ('by these presents'). ONLY if that is true is their ratification valid. If true, their ratification was valid, and the states retained the right to unilaterally resume their delegated powers at will.
If not true, then their ratification was null and void.
AFTER their ratification came SUGGESTED/proposed amendments to the Constitution.
