A yet more important clause in the Constitution shows conclusively the supremacy and national character of the government; namely that giving it the power of changing and extending its authority to whatever extent it chooses by amendments, provided they are accepted by the Legislatures of three quarters of the States. By amendments made in this manner the United States can take whatever authority it pleases from the States. It can give its government a veto over the laws of the separate States, appoint the executive officers of a State—powers proposed in the convention that made the Constitution. The only limit in the Constitution to the extension of the government’s power by amendments is that no State without its consent could be deprived of its equal suffrage in the Senate, and the importation of slaves until 1808 should not be prohibited. Under this provision the General Government, with the concurrence of three fourths of the Legislatures of the States, has an authority that no State government has. None of the State constitutions grant its Legislature the right to extend its powers over counties, cities, and towns; it must go to the people for that.

How can it be said that sovereignty remains in a State, when it gives to its associates the right to make all its laws if only three quarters of them so elect? The granting by a community of power to a government over it to control it, as it pleases, takes away the very foundation of sovereign right; and objection was made to this clause for this very reason. In the convention Elbridge Gerry, a prominent delegate from Massachusetts, afterwards Governor of that State and Vice-President of the United States, objected because the Constitution is paramount to the State constitutions, and that two thirds of the States may introduce innovations that would subvert the State constitution altogether.[19] It is by the power given in this clause, that after the war of secession slavery was abolished through the acceptance by the States of amendments to that effect. The proclamation of Lincoln abolishing slavery in the States in insurrection on January 1, 1863, did not give liberty to the slaves in Delaware, Maryland, Missouri and Kentucky, and parts of other States, that were not in rebellion. Many, perhaps all, of these States abolished slavery before the amendments were passed.

The only authority given by the Constitution to States is this power of amending it by the concurrence of State Legislatures in propositions made by the Congress of the United States or the Legislatures of three fourths of the States, and also the right of equal representation in the Senate, and that in the election of President the vote is by electors appointed in such manner as the State Legislature may direct.

The provision forbidding a State from emitting bills of credit, passing any bill of attainder, ex post facto law, or law impairing the obligation of contracts, are a restriction that sovereign nations would never have submitted to.

When a foreigner becomes a citizen, he abjures his allegiance to his native country, and the oath he takes is before a United States officer to the United States, not to the State in which he is naturalized. Finally, by the Constitution the President is made the commander-in-chief of the army and navy of the United States, and of the militia of the several States. While an oath or affirmation is required of every Senator or Representative, of every executive and judicial officer of the United States and of every State, to support the Constitution, the President alone—the one having the supreme military power over all forces on land or sea—must swear or affirm that he will faithfully execute the office, and “to the best of my ability, preserve, protect, and defend the Constitution of the United States”; not to keep from encroachment upon the rights of the States, but to preserve, protect, and defend the Constitution. Can it be said that it is not to be preserved over its citizens and States that are in arms to subvert or resist its laws and supremacy?

Jefferson, in the time of the Confederacy, when the States were neglecting to pay the requisitions made of them, recommended that the Continental Congress should show its teeth and send a frigate into the ports of a delinquent State; but the new Constitution intended to draw the teeth of the States by prohibiting them from keeping troops or ships of war; and it reserved to the national government the right “to raise and support armies”; “to provide and maintain a navy”; and gave it the power of “calling forth the militia to execute the laws of the Union, suppress insurrection, and repel invasion.” Thus the Constitution added to the supremacy of the new government the power to enforce it, and took from the States the power, as far as it could consistently with freedom, of resistance.

The government of the Confederacy depended upon the several State governments, their soldiers, and their contributions; it had no direct control over the people; from the failure of the State government to make the required contributions and enforce its decrees it was fast falling into total inefficacy. We have shown that the new government, established by the people of each State over themselves and the people of the other States, had by its Constitution all the powers necessary for a national government, and State governments were prohibited from the exercise of conflicting powers; that waging war against that government was treason, thus affirming that they, the people of each State who established it, owed allegiance and were subjects of the government; they, the people, also declared in the Constitution, that the judiciary of their general government should have authority over every case and question arising under its laws and acts; further, they gave that judiciary and the government the power to enforce their laws and the authority over every individual in its domain; and finally they expressly declared the supremacy of the government and its laws over all State laws and State constitutions.

The departments of the government established by the Constitution are three in number: the Legislative (Congress), to make the laws and to pass the acts for the carrying it on; the Executive (the President and the officers under him), to administer it, to carry into effect its laws and acts, and represent it in its dealings with other countries; and thirdly the Judiciary, to decide upon all controversies arising under the laws and acts of the government.

A department, however, in some instances has an authority in the others; the President, the chief executive officer, has the right of veto, and his principal appointments, especially those of the judiciary and foreign ministers, are subject to the approval of the Senate.
