James Madison, Federalist, no. 45, 313--1426 Jan. 1788
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, negociation, and foreign commerce; with which last the power of taxation will for the most part be connected. The powers reserved to the several States will extend to all the objects, which, in the ordinary course of affairs, concern the lives, liberties and properties of the people; and the internal order, improvement, and prosperity of the State.
The operations of the Federal Government will be most extensive and important in times of war and danger; those of the State Governments, in times of peace and security. As the former periods will probably bear a small proportion to the latter, the State Governments will here enjoy another advantage over the Federal Government. The more adequate indeed the federal powers may be rendered to the national defence, the less frequent will be those scenes of danger which might favour their ascendency over the governments of the particular States.
If the new Constitution be examined with accuracy and candour, it will be found that the change which it proposes, consists much less in the addition of NEW POWERS to the Union, than in the invigoration of its ORIGINAL POWERS. The regulation of commerce, it is true, is a new power; but that seems to be an addition which few oppose, and from which no apprehensions are entertained. The powers relating to war and peace, armies and fleets, treaties and finance, with the other more considerable powers, are all vested in the existing Congress by the articles of Confederation. The proposed change does not enlarge these powers; it only substitutes a more effectual mode of administering them. The change relating to taxation, may be regarded as the most important: And yet the present Congress have as compleat authority to REQUIRE of the States indefinite supplies of money for the common defence and general welfare, as the future Congress will have to require them of individual citizens; and the latter will be no more bound than the States themselves have been, to pay the quotas respectively taxed on them. Had the States complied punctually with the articles of confederation, or could their compliance have been enforced by as peaceable means as may be used with success towards single persons, our past experience is very far from countenancing an opinion that the State Governments would have lost their constitutional powers, and have gradually undergone an entire consolidation. To maintain that such an event would have ensued, would be to say at once, that the existence of the State Governments is incompatible with any system whatever that accomplishes the essential purposes of the Union.
