Hearst was on the left wing of the Progressive Movement, speaking on behalf of the working class (who bought his papers) and denouncing the rich and powerful (who disdained his editorials). With the support of Tammany Hall (the regular Democratic organization in Manhattan), Hearst was elected to Congress from New York in 1902 and 1904. He made a major effort to win the 1904 Democratic nomination for president, losing to conservative Alton B. Parker. Breaking with Tammany in 1907, Hearst ran for mayor of New York City under a third party of his own creation, the Municipal Ownership League. Tammany Hall exerted its utmost to defeat him.
