But if a republican form of government is that in which all the men have a share in the public power, the slave-holding States will not alone retire from the Union. The constitutions of some of the other States do not sanction universal suffrage, or universal eligibility. They require citizenship, and age, and a certain amount of property, to give a title to vote or to be voted for; and they who have not those qualifications are just as much disfranchised, with regard to the government and its power, as if they were slaves. They have civil rights indeed (and so have slaves in a less degree; ) but they have no share in the government. Their province is to obey the laws, not to assist in making them. All such States must therefore be forisfamiliated with Virginia and the rest, or change their system. For the Constitution being absolutely silent on those subjects, will afford them no protection. The Union might thus be reduced from an Union to an unit. Who does not see that such conclusions flow from false notions--that the true theory of a republican government is mistaken--and that in such a government rights, political and civil, may be qualified by the fundamental law, upon such inducements as the freemen of the country deem sufficient? That civil rights may be qualified as well as political, is proved by a thousand examples. Minors, resident aliens, who are in a course of naturalization--the other sex, whether maids, or wives, or widows, furnish sufficient practical proofs of this. * * * * * We are next invited to study that clause of the Constitution which relates to the migration or importation, before the year 1808, of such persons as any of the States then existing should think proper to admit. It runs thus: "The migration or importation of such persons as any of the States now existing shall think proper to admit, shall not be prohibited by the Congress prior to the year one thousand eight hundred and eight, but a tax or duty may be imposed on such importation not exceeding ten dollars for each person." It is said that this clause empowers Congress, after the year 1808, to prohibit the passage of slaves from State to State, and the word "migration" is relied upon for that purpose. * * * * *
