The serious aspect of the matter, however, to Douglas was not the criticism of the Republicans, but the view taken by Southern Democratic leaders, of his "Freeport doctrine," or doctrine of "unfriendly legislation." His opposition to the Lecompton Constitution in the Senate, grievous stumbling-block to their schemes as it had proved, might yet be passed over as a reckless breach of party discipline; but this new announcement at Freeport was unpardonable doctrinal heresy, as rank as the abolitionism of Giddings and Lovejoy. The Freeport joint debate took place August 27, 1858. When Congress convened on the first Monday in December of the same year, one of the first acts of the Democratic senators was to put him under party ban by removing him from the chairmanship of the Committee on Territories, a position he had held for eleven years. In due time, also, the Southern leaders broke up the Charleston convention rather than permit him to be nominated for President; and, three weeks later, Senator Benjamin of Louisiana frankly set forth, in a Senate speech, the light in which they viewed his apostacy: "We accuse him for this, to wit: that having bargained with us upon a point upon which we were at issue, that it should be considered a judicial point; that he would abide the decision; that he would act under the decision, and consider it a doctrine of the party; that having said that to us here in the Senate, he went home, and, under the stress of a local election, his knees gave way; his whole person trembled. His adversary stood upon principle and was beaten; and, lo! he is the candidate of a mighty party for the presidency of the United States. The senator from Illinois faltered. He got the prize for which he faltered; but, lo! the grand prize of his ambition to-day slips from his grasp, because of his faltering in his former contest, and his success in the canvass for the Senate, purchased for an ignoble price, has cost him the loss of the presidency of the United States."
