Hiram W. Johnson, backed by women's suffrage activist and early feminist Katherine Philips Edson, was a candidate for California governor in 1910, the Progressive Party vice presidential nominee in 1912, and was reelected as Governor of California on the Progressive ticket in 1914. In 1916, he was elected as a Progressive to the U.S. Senate and continued his affiliation with the state party throughout his decades in the Senate, while simultaneously winning the Republican nomination. While Johnson was personally close to Theodore Roosevelt, he was much closer ideologically to Robert La Follette. Johnson sat out the general election in 1924 after unsuccessfully challenging President Calvin Coolidge for the Republican nomination. Johnson personally disliked La Follette but grudgingly admired his quixotic third-party bid and generally agreed with his 1924 platform.
