In the next place, the state governments are, by the very theory of the constitution, essential constituent parts of the general government. They can exist without the latter, but the latter cannot exist without them.
Joseph Story, Commentaries on the Constitution, 1833

[Dead Corpse]

It is an established rule of construction, where a phrase will bear either of two meanings to give it that which will allow some meaning to the other parts of the instrument, and not that which will render all the others useless. Certainly no such universal power was meant to be given to them. It was intended to lace them up straightly with in the enumerated powers, and those without which, as means, these powers could not be carried into effect.
Thomas Jefferson, Opinion on a National Bank, February 15, 1791
