The United States presidential election of 1908 was held on November 3, 1908. Popular incumbent President Theodore Roosevelt, honoring a promise not to seek a third term, persuaded the Republican Party to nominate William Howard Taft, his close friend and Secretary of War, to become his successor. Having badly lost the 1904 election with a conservative candidate, the Democratic Party turned to two-time nominee William Jennings Bryan, who had been defeated in 1896 and 1900 by Republican William McKinley. Despite his two previous defeats, Bryan remained extremely popular among the more liberal and populist elements of the Democratic Party. Despite running a vigorous campaign against the nation's business elite, Bryan suffered the worst loss in his three presidential campaigns, and Taft won by a comfortable margin.
