Or this for the commerce clause:
3. To regulate commerce with foreign nations, and among the several States, and with the Indian tribes; but neither this, nor any other clause contained in the Constitution, shall ever be construed to delegate the power to Congress to appropriate money for any internal improvement intended to facilitate commerce; except for the purpose of furnishing lights, beacons, and buoys, and other aids to navigation upon the coasts, and the improvement of harbors and the removing of obstructions in river navigation; in all which cases such duties shall be laid on the navigation facilitated thereby as may be necessary to pay the costs and expenses thereof.
Well clearly, the protectionism of times past were clearly uncontitutional ie “steel in the 90’s”, “sugar now”, and the comerce clause can not be used to make government sponsored improvments to the interior. That makes the federal highway system potentional unconstitutional.
Clearly the states rights have been completely usurpted.
