Those powers not granted to the Fed, remain with the states. The original soveriegn rule.
Interesting that you would quote something that is 180 degrees out of kilter and then agree with it.
Anyone who has studied the history of the nation knows that the Constitution was created as a means of vastly INCREASING federal power while removing all significant aspects of full sovereignty from the states.
Madison clearly explains why a Confederation composed of fully sovereign states MUST fail and the history of ours showed how it DID fail resulting in the call for the Convention and a new Constitution.
The tenth amendment changes none of that and merely refers to the rights involving local police powers, health and welfare concerns or concerns affecting ONLY those within a particular state.
