Douglas had little trouble in making answer in an _ad captandum_ manner to all Mr. Lincoln's questions save one. The crucial test was applied when Mr. Lincoln asked him "if the people of a Territory can, in any lawful way, against the wishes of any citizen of the United States, exclude slavery from their limits prior to the formation of a State constitution?" In the first debate, when Douglas had the opening, he had, in the popular judgment, rather worsted Mr. Lincoln. His greater familiarity with the arts if not the tricks of the stump had given him an advantage. But now Mr. Lincoln had the opening, and he threw Mr. Douglas upon the defensive by the question which reached the very marrow of the controversy. Mr. Lincoln had measured the force of his question, and saw the dilemma in which it would place Douglas. Before the meeting he said, in private, that "Douglas could not answer that question in such way as to be elected both Senator and President. He might so answer it as to carry Illinois, but, in doing so, he would irretrievably injure his standing with the Southern Democracy." Douglas quickly realized his own embarrassment. He could not, in the face of the Supreme-Court decision, declare that the people of the Territory could exclude slavery by direct enactment. To admit, on the other hand, that slavery was fastened upon the Territories, --past all hope of resistance or protest on the part of a majority of the citizens--would be to concede the victory to Mr. Lincoln without further struggle. Between these impossible roads Douglas sought a third. He answered that, regardless of the decision of the Supreme Court, "the people of a Territory have the lawful means to introduce or exclude slavery as they choose, for the reason that slavery cannot exist unless supported by local police regulations. Those police regulations can only be established by the local legislature; and, if the people are opposed to slavery, they will, by unfriendly legislation, effectually prevent the introduction."
