If anything be found in the national Constitution, either by original provision or subsequent interpretation, which ought not to be in it, the people know how to get rid of it. If any construction, unacceptable to them, be established, so as to become practically a part of the Constitution, they will amend it at their own sovereign pleasure. But while the people choose to maintain it as it is, while they are satisfied with it, and refuse to change it, who has given, or who can give, to the State legislatures a right to alter it, either by interference, construction, or otherwise? Gentlemen do not seem to recollect that the people have any power to do anything for themselves. They imagine there is no safety for them, any longer than they are under the close guardianship of the State legislatures. Sir, the people have not trusted their safety in regard to the general Constitution to these hands. They have required other security, and taken other bonds. They have chosen to trust themselves, first, to the plain words of the instrument, and to such construction as the government themselves, in doubtful cases, should put on their own powers, under their oaths of office, and subject to their responsibility to them; just as the people of a State trust their own State governments with a similar power. Secondly, they have reposed their trust in the efficacy of frequent elections, and in their own power to remove their own servants and agents whenever they see cause. Thirdly, they have reposed trust in the judicial power, which, in order that it might be trustworthy, they have made as respectable, as disinterested, and as independent as was practicable. Fourthly, they have seen fit to rely, in case of necessity, or high expediency, on their known and admitted power to alter or amend the Constitution, peaceably and quietly, whenever experience shall point out defects or imperfections. And, finally, the people of the United States have at no time, in no way, directly or indirectly, authorized any State legislature to construe or interpret _their_ high instrument of government; much less to interfere, by their own power, to arrest its course and operation. If, Sir, the people in these respects had done otherwise than they have done, their Constitution could neither have been preserved, nor would it have been worth preserving. And if its plain provisions shall now be disregarded, and these new doctrines interpolated in it, it will become as feeble and helpless a being as its enemies, whether early or more recent, could possibly desire. It will exist in every State but as a poor dependent on State permission. It must borrow leave to be; and will be, no longer than State pleasure, or State discretion, sees fit to grant the indulgence, and to prolong its poor existence.
