And the war was a terrible war, but it was a war for human freedom, and if the South had succeeded and if slavery had been extended, the United States, or part of it, might very well have been on the side of Hitler in the Second World War. We would not have been the bastion of freedom we have been in the twentieth century.

Now there's a little story to that. Chief Justice Taney, in the Dred Scott decision—which said that the Missouri Compromise restriction of slavery in 1820 and any other one, was unconstitutional—said that there was no power in the Congress to forbid slavery in the territories. And he added as a kind of obiter dictum that the only power of Congress over slavery in the territories was the power coupled with the duty of protecting the owner and his rights. Now the seven states of the Deep South interpreted that to mean that the police power of the federal government had to guarantee the integrity of the property of any slave owner going into any United States territory.

Douglas accepted Dred Scott, and in Dred Scott, the Chief Justice had said that the right to own slaves is expressly affirmed in the Constitution. And Lincoln said in the debates that it was implied but not expressly affirmed. The argument against any restriction on slavery was that any right expressly affirmed in the Constitution takes precedent over any law or regulation in any jurisdiction whatever. (Remember, the supremacy clause in Article VI of the Constitution says that this Constitution, and the laws and treaties made in pursuance thereof, are the supreme law of land—anything in any law or a constitution of any state to the contrary not withstanding.)
