The national situation was still further complicated by the disintegration and chaos into which the two old parties were then tumbling, and by the fierce rivalries and jealousies within them of party leaders at the North. All the conditions seemed to favor southern aggression--the commission of some monstrous crime against liberty. Webster had gone to his long account, dishonored and broken-hearted. The last of the three supreme voices of the early senatorial splendor of the republic was now hushed in the grave. As those master lights, Calhoun, Webster and Clay, vanished one after another into the void, darkness and uproar increased apace. About this time the most striking and sinister figure in American Party history loomed into greatness. Stephen A. Douglas was a curious and grim example of the survival of viking instincts in the modern office seeker. On the sea of politics he was a veritable water-dog, daring, unscrupulous, lawless, transcendently able, and transcendently heartless. The sight of the presidency moved him in much the same way as did the sight of the effete and wealthy lands of Latin Europe moved his roving, robber prototypes eleven centuries before. It stirred every drop of his sea-wolf's blood to get possession of it. His "Squatter Sovereignty Dogma" was in truth a pirate boat which carried consternation to many an anxious community in the free states. It was with such an ally that the slave power undertook the task of repealing the Missouri Compromise. The organization of the northern section of the Louisiana Purchase into the territories of Kansas and Nebraska was made the occasion for abolishing the old slave line of 1820. That line had devoted all of that land to freedom. Calhoun, bold as he was, had never ventured to counsel the abrogation of that solemn covenant between the sections. The South, to his way of thinking, had got the worst of the bargain, had in fact been overreached, but a bargain was a bargain, and therefore he concluded that the slave states should stand by their plighted faith until released by the free. That which the great Nullifier hesitated to counsel, his disciples and successors dared to do. The execution of the plot was adroitly committed to the hands of Douglas, under whose leadership the movement for repeal would appear to have been started by the section which was to be injured by it. Thus the South would be rescued from the moral and political consequences of an act of bad faith in dealing with her sister section.
