18 Jan Reserved to the States or to the People

“I consider the foundation of the Constitution as laid on this ground: That ‘all powers not delegated to the United States, by the Constitution, nor prohibited by it to the States, are reserved to the States or to the people.’ To take a single step beyond the boundaries thus specially drawn around the powers of Congress, is to take possession of a boundless field of power, no longer susceptible of any definition.” – Thomas Jefferson
