The whole structure of Caste and Oligarchy, as founded on two words, may be dismissed. It is hard even to think of it without impatience, to speak of it without denouncing it as unworthy of human head or human heart. There are honorable Senators who shrink from any direct argument on these two words, and, wrapping themselves in pleonastic phrase, content themselves with the general assertion, that power over suffrage belongs to the States. But they cannot maintain this conclusion without founding on these two words,--insisting that color may be a “qualification,” and that under the narrow power to make “regulations” a race may be broadly disfranchised. To this wretched pretension are they driven. And now, if there be any such within the sound of my voice, I ask the question directly,--Can “color,” whether of hair, eyes, or skin, be a “qualification” under our National Constitution? under the pretence of making “regulations” of elections, can a race be disfranchised? With all the power derived from both these words, can any State undertake to establish a Caste and organize an Oligarchy of the Skin? To put these questions is to answer them. * * * * * Such is the case as presented by the champions. But looking at the National Constitution, we shall be astonished still more at this pretension. On other occasions I have gone over the whole case of Human Rights vs. State Rights under the National Constitution. For the present I content myself with allusions only to the principal points. It is under the National Constitution that the champions set up their pretension; therefore to the National Constitution I go. And I begin by appealing to the letter, which from beginning to end does not contain one word recognizing “color.” Its letter is blameless; and its spirit is not less so. Surely a power to disfranchise for color must find some sanction in the Constitution. There must be some word of clear intent under which this terrible prerogative can be exercised. This conclusion of reason is reinforced by the positive text of our Magna Charta, the Declaration of Independence, where it is expressly announced that all men are equal in rights, and that just government stands only on the consent of the governed. In the face of the National Constitution, interpreted, first by itself, and then by the Declaration of Independence, how can this pretension prevail? But there are positive texts of the National Constitution, refulgent as the Capitol itself, which forbid it with sovereign, irresistible power, and invest Congress with all needful authority to maintain the prohibition.
