to the left won the admiration of many, it also created enemies such as George Brinton McClellan Harvey, a former Wilson supporter who had close ties to Wall Street. In July 1911, Wilson brought William Gibbs McAdoo and "Colonel" Edward M. House in to manage the campaign. Prior to the 1912 Democratic National Convention, Wilson made a special effort to win the approval of three-time Democratic presidential nominee William Jennings Bryan, whose followers had largely dominated the Democratic Party since the 1896 presidential election. Speaker of the House Champ Clark of Missouri was viewed by many as the front-runner for the nomination, while House Majority Leader Oscar Underwood of Alabama also loomed as a challenger. Clark found support among the Bryan wing of the party, while Underwood appealed to the conservative Bourbon Democrats, especially in the South. In the 1912 Democratic Party presidential primaries, Clark won several of the early contests, but Wilson finished strong with victories in Texas, the Northeast, and the Midwest. On the first presidential ballot of the Democratic convention, Clark won a plurality of delegates; his support continued to grow after the New York Tammany Hall machine swung behind him on the tenth ballot.

Wilson finally won two-thirds of the vote on the convention's 46th ballot, and Marshall became Wilson's running mate.

The fourth candidate was Eugene V. Debs of the Socialist Party.

Roosevelt emerged as Wilson's main challenger, and Wilson and Roosevelt largely campaigned against each other despite sharing similarly progressive platforms that called for an interventionist central government. Wilson directed campaign finance chairman Henry
