The Dred Scott decision covers the whole question, and declares that each State has the right to settle this question of suffrage for itself, and all questions as to the relations between the white man and the negro. Judge Taney expressly lays down the doctrine. I receive it as law, and I say that while those States are adopting regulations on that subject disgusting and abhorrent, according to my views, I will not make war on them if they will mind their own business and let us alone.
I now come back to the question, why cannot this Union exist forever divided into Free and Slave States, as our fathers made it? It can thus exist if each State will carry out the principles upon which our institutions were founded; to-wit, the right of each State to do as it pleases, without meddling with its neighbors. Just act upon that great principle, and this Union will not only live forever, but it will extend and expand until it covers the whole continent, and makes this confederacy one grand, ocean-bound Republic. We must bear in mind that we are yet a young nation, growing with a rapidity unequalled in the history of the world, that our national increase is great, and that the emigration from the old world is increasing, requiring us to expand and acquire new territory from time to time, in order to give our people land to live upon. If we live upon the principle of State rights and State sovereignty, each State regulating its own affairs and minding its own business, we can go on and extend indefinitely, just as fast and as far as we need the territory. The time may come, indeed has now come, when our interests would be advanced by the acquisition of the Island of Cuba. When we get Cuba, we must take it as we find it, leaving the people to decide the question of slavery for themselves, without interference on the part of the Federal Government or of any State of this Union. So, when it becomes necessary to acquire any portion of Mexico or Canada, or of this continent or the adjoining islands, we must take them as we find them, leaving the people free to do as they please,to have slavery or not, as they choose. I never have inquired and never will inquire whether a new State, applying for admission, has slavery or not
