Greeley supported Ulysses S. Grant during the first years of his administration but came to resent what he considered Grant's subservience to that wing of the Republican party in New York state dominated by Roscoe Conkling. In 1871 he began to encourage the movement that grew into the Liberal Republican party and avidly sought the nomination for President in 1872. Although the Democrats also endorsed him, many of them refused to support a man who had spent his life opposing the principles for which they had stood, especially that of a tariff for revenue only. During the campaign all Greeley's shortcomings were caricatured, and he was denounced as a traitor and a crank. Despite his strenuous campaign he was overwhelmingly defeated by Grant. His disappointment at the result and his sorrow at the death of his wife a few days before the election unbalanced his mind, and he died insane on Nov. 29, 1872.
