The next joint debate occurred nearly three weeks later down in Egypt. By slow stages, speaking incessantly at all sorts of meetings, Douglas and Lincoln made their several ways through the doubtful central counties to Jonesboro in Union County. This was the enemy's country for Lincoln; and by reason of the activities of United States Marshal Dougherty, a Buchanan appointee, the county was scarcely less hostile to Douglas. The meeting was poorly attended. Those who listened to the speakers were chary of applause and appeared politically apathetic.[731] Douglas opened the debate by a wild, unguarded appeal to partisan prejudices. Knowing his hearers, he was personally vindictive in his references to Black Republicans in general and to Lincoln in particular. He reiterated his stock arguments, giving new vehemence to his charge of corrupt bargain between Trumbull and Lincoln by quoting Matheny, a Republican and "Mr. Lincoln's especial and confidential friend for the last twenty years."[732] Lincoln begged leave to doubt the authenticity of this new evidence, in view of the little episode at Ottawa, concerning the Springfield resolutions. At all events the whole story was untrue, and he had already declared it to be such.[733] Why should Douglas persist in misrepresenting him? Brushing aside these lesser matters, however, Lincoln addressed himself to what had now come to be known as Douglas's Freeport doctrine. "I hold," said he, "that the proposition that slavery cannot enter a new country without police regulations is historically false.... There is enough vigor in slavery to plant itself in a new country even against unfriendly legislation. It takes not only law but the enforcement of law to keep it out." Moreover, the decision of the Supreme Court in the Dred Scott case had created constitutional obligations. Now that the right of property in slaves was affirmed by the Constitution, according to the Court, how could a member of a territorial legislature, who had taken the oath to support the Constitution, refuse to give his vote for laws necessary to establish slave property? And how could a member of Congress keep his oath and withhold the necessary protection to slave property in the Territories?[734] Of course Lincoln was well aware that Douglas held that the Court had decided only the question of jurisdiction in the Dred Scott case; and that all else was a mere _obiter dictum_. Nevertheless, "the Court did pass its opinion.... If they did not decide, they showed what they were ready to decide whenever the matter was before them. They used language to this effect: That inasmuch as Congress itself could not exercise such a power [_i.e._, pass a law prohibiting slavery in the Territories], it followed as a matter of course that it could not authorize a Territorial Government to exercise it; for the Territorial Legislature can do no more than Congress could do."[735]
