Douglas had no great difficulty with the first three questions, and the fourth--the second, as Lincoln read them--he had in fact answered several times already, and in a way to please the Democrats of Illinois. But Lincoln, contrary to the advice of his friends, pressed it on him again with a view to the "all hail hereafter," for it was meant to bring out the inconsistency of the principle of popular sovereignty with the Dred Scott decision, and the difference between the Northern and the Southern Democrats. Douglas answered it as he had before. The people of a Territory, through their legislature, could by unfriendly laws, or merely by denying legislative protection, make it impossible for a slave-owner to hold his slaves among them, no matter what rights he might have under the Constitution. Lincoln declared that the answer was historically false, for slaves had been held in Territories in spite of unfriendly legislation, and pointed out that if the Dred Scott decision was right the members of a territorial legislature, when they took an oath to support the Constitution, bound themselves to grant slavery protection. Later, in a fifth and last question, he asked whether, in case the slave-owners of a Territory demanded of Congress protection for their property, Douglas would vote to give it to them. But Douglas fell back upon his old position that Congress had no right to intervene. He would not break with his supporters in Illinois, but by his "Freeport Doctrine" of unfriendly legislation he had broken forever with the men who were now in control of his party in the Southern States.
