To say that a State can make a man a slave, is only another mode of saying that a State can deprive the United States of a citizen, and abolish the government of the United States, so far as that citizen is concerned. And to say that a State can deprive the United States of one citizen, is equivalent to saying that a State can deprive the government of the United States of all its citizens, within the State.
And to say that a State can deprive the government; of the United States of all its citizens, within the State, is equivalent to saying that the State can entirely abolish the United States government, within such State. This is the necessary conclusion of the doctrine, that the States can make a slave of any individual, who would otherwise be a citizen of the United States.
