That judgment of him and of the bill was probably accepted by a majority of his contemporaries. For lack of Southern support, he had missed the Democratic nomination in 1852. It seemed clear that whatever Northern candidate the South should prefer would be nominated in 1856. His rivals were all, in one way or another, commending themselves to the South. Pierce was hand in glove with Davis and other Southern leaders. Marcy, in the Department of State, and Buchanan, in a foreign mission, were both working for the annexation of Cuba, a favorite Southern measure. It was suspected that Cass, old as he was, had it in mind to move the repeal when Douglas went ahead of him. The contemporaries of Douglas were under a necessity to judge his motives, for they had to pass upon his fitness for high office and great responsibilities, and no other motive than ambition was so natural and obvious an explanation of his course. But it is questionable if any such positive judgment as was necessary, and therefore right, in his contemporaries, is obligatory upon historians. What he did was in accord with a political principle which he had avowed, and it was not in conflict with any moral principle he had ever avowed, for he did not pretend to believe that slavery was wrong. True, he had once thought the Missouri Compromise a sacred compact; but there were signs that he had abandoned that opinion. It is enough to decide that he took a wrong course, and to point out how ambition may very well have led him into it. It is too much to say he knew it was wrong, and took it solely because he was ambitious.
