California was a leader in the Progressive Movement from the 1890s into the 1920s. A coalition of reform-minded Republicans, especially in southern California, coalesced around Thomas Bard (1841–1915). Bard's election in 1899 as United States senator enabled the anti-machine Republicans to sustain a continuing opposition to the Southern Pacific Railway's political power in California. They helped nominate George C. Pardee for governor in 1902 and formed the "Lincoln–Roosevelt League". In 1910 Hiram W. Johnson won the campaign for governor under the slogan "Kick the Southern Pacific out of politics." In 1912 Johnson became the running mate for Theodore Roosevelt on the new Bull Moose Party ticket.
