If Congress would just follow the US Constitution, that they all sworn to uphold, there would be no pork. If the citizens of Nashville, Tennessee, and the Tennessee legislature, decided that Nashville needed a mass transit system, and the taxpayers of the city and state were willing to fund it, great, but the citizens of Iowa or New York should not have to fund it, because it would be a project for the benefit of the state, or city, not the citizens of the collective states that make up the United States, so it should be funded by the city and state it benefits, not the federal government. By the same token, the citizens of Tennessee, or Iowa, should not have to fund mass transit in New York. If we would just read the Federalist Papers, we would find out what the Framers of our Constitution intended. "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." - James Madison, Federalist Paper No. 25, 1788 - considered the 'father of the Constitution'
