Owen J. Roberts, United States v. Butler (297 U.S. 1…
“ The question is not what power the federal government ought to have, but what powers in fact have been given by the people. It hardly seems necessary to reiterate that ours is a dual form of government; that in every state there are two governments; the state and the United States. Each state has all governmental powers save such as the people, by their Constitution, have conferred upon the United States, denied to the states, or reserved to themselves. The federal union is a government of delegated powers. ”
