The new party was known for taking advanced positions on progressive reforms and attracting some leading reformers . After the party's defeat in the 1912 presidential election, it went into rapid decline, disappearing by 1918 . The Progressive Party was nicknamed the "Bull Moose Party" after journalists quoted Roosevelt saying that he felt "fit as a bull moose" following an assassination attempt on the campaign trail shortly after the new party was formed . </P> <P> As a member of the Republican Party, Roosevelt had served as President from 1901 to 1909, becoming increasingly progressive in the later years of his presidency . In the 1908 presidential election, Roosevelt helped ensure that he would be succeeded by Secretary of War Taft . After Taft took office, he hewed closer to the conservative wing of the party and this and other actions alienated Roosevelt from his former friend . Progressive Republican leader Robert La Follette had already announced a challenge to Taft for the 1912 Republican nomination, but many of his supporters shifted to Roosevelt after the former President decided to seek a third presidential term, which was permissible under the Constitution prior to the ratification of the Twenty - second Amendment . At the 1912 Republican National Convention, Taft narrowly defeated Roosevelt for the party's presidential nomination . After the convention, Roosevelt, Frank Munsey, George Walbridge Perkins and other progressive Republicans established the Progressive Party and nominated a ticket of Roosevelt and Hiram Johnson of California at the 1912 Progressive National Convention . The new party attracted several Republican officeholders, although nearly all of them remained loyal to the Republican Party--in California, Johnson and the Progressives took control of the Republican Party . </P>
