With Roosevelt's help, Taft had little opposition for the Republican nomination for president in 1908 and easily defeated William Jennings Bryan for the presidency that November. In the White House, he focused on East Asia more than European affairs and repeatedly intervened to prop up or remove Latin American governments. Taft sought reductions to trade tariffs, then a major source of governmental income, but the resulting bill was heavily influenced by special interests. His administration was filled with conflict between the conservative wing of the Republican Party, with which Taft often sympathized, and the progressive wing, toward which Roosevelt moved more and more. Controversies over conservation and antitrust cases filed by the Taft administration served to further separate the two men. Roosevelt challenged Taft for renomination in 1912. Taft used his control of the party machinery to gain a bare majority of delegates and Roosevelt bolted the party. The split left Taft with little chance of re-election and he took only Utah and Vermont in Wilson's victory.
