But the career of Douglas in Washington was the career of an opportunist, at once full of good and full of evil, full of right and full of wrong. He was a born politician, an expert manager of men and a natural machine builder. Many others outranked Douglas in set speeches, but few equalled him in "catch as catch can" methods of the politician. What Douglas prided himself upon was his skill in getting through the committee measures that were difficult to pass. When it became necessary to get a man's vote for his measure, Douglas would put that man up as a leader, give him the glory, obliterate himself, and after the bill was passed, hop up like a jack in the pulpit, as the real manager who manoeuvred the bill through the Senate. He spent two years on the legislation that brought about the Illinois Central Railroad, and as long a time in founding the University of Chicago. Often Douglas did things that he believed to be morally wrong because he discovered that they were politically necessary. For example, a reaction followed upon the election of the Democrat, James K. Polk, to the presidency. When his leadership was imperilled, Polk cast about for some issue that would bring together the remnants of his party, and restore leadership, and he hit upon the device of the Mexican War. No party was ever defeated that was fighting a war for the defense of the country. Douglas criticized Polk most sharply, charged the war upon Polk as a crime against the people, and yet, under the whip of party policy, Douglas supported Polk. Slowly he deteriorated in his moral fibre. One by one the moral lights seem to have gone out. He was intoxicated by his own success. Ambition deluded him. He began to follow the will-o'-the-wisp, the light that rises from putrescence and decay in the swamp, and forgot the eternal stars in God's sky. In 1854 he entered the valley of decision, and like the rich young ruler made the great refusal, and chose compromise instead of principle. Later Douglas led his party along a false route, and became a mistaken leader.
