James Madison, the acknowledged father of the Constitution, explained in Federalist Paper No. 45: "The powers delegated by the proposed Constitution to the federal government are few and defined. Those which are to remain in the State governments are numerous and indefinite. The former will be exercised principally on external objects, as war, peace, negotiation, and foreign commerce. ... The powers reserved to the several States will extend to all the objects which in the ordinary course of affairs, concern the lives and liberties, and properties of the people, and the internal order, improvement and prosperity of the State."
" Article I, Section 8 of our Constitution lists the activities for which Congress is authorized to tax and spend. Nowhere on that list is authority for Congress to tax and spend for: prescription drugs, Social Security, public education, farm subsidies, bank and business bailouts, food stamps and other activities that represent roughly two-thirds of the federal budget. Neither is there authority for congressional mandates to the states and people about how they may use their land, the speed at which they can drive, whether a library has wheelchair ramps and the gallons of water used per toilet flush. The list of congressional violations of both the letter and spirit of the Constitution is virtually without end. Our derelict Supreme Court has given Congress sanction to do anything upon which they can muster a majority vote."
