"The federal and State governments are in fact but different agents and trustees of the the people, constituted with different powers, and designed for different purposes. The adversaries of the Constitution seem to have lost sight of the people altogether in their reasonings on this subject; and to have viewed these different establishments, not only as mutual rivals and enemies, but as uncontrolled by any common superior in their efforts to usurp the authorities of each other. These gentlemen must here be reminded of their error. They must be told that the ultimate authority, wherever the derivative may be found, resides in the people alone...."
--James Madison, Federalist No. 46
