In the constitutional scheme, federalism provides an avenue for local self-determination, in addition to a vertical check on government oppression, with the states serving as a localized control on the centralized national government. Under the framers’ view of federalism, as expressed in the Tenth Amendment, the national government would exert supreme authority only within the limited scope of its enumerated powers; the states meanwhile would exercise the remainder of sovereign authority, subject to the restraint of interstate competition from other states.
