Theodore Roosevelt was president of the United States until 1909. When he left office, William Howard Taft was chosen to run and won the presidency for the Republican Party. In 1912, Roosevelt was unhappy with Taft's time in office and put his name forward to become the Republican Party's nominee again. The Party chose to stick with Taft. This angered Roosevelt who walked out of the convention and then formed his own party, the Progressive Party in protest. Hiram Johnson was chosen as his running mate.
.True to Roosevelt's progressive beliefs, the platform of the party called for major reforms including women's suffrage, social welfare assistance for women and children, farm relief, revisions in banking, health insurance in industries, and worker's compensation. The party also wanted an easier method to amend the constitution.
While the Bull Moose Party lost at the national level in 1912, it continued putting candidates on the ballot at the state and local elections. However, these candidates did poorly in 1914. The party did hold a convention in 1916 and nominated Roosevelt to run again. When he refused, the party tried to give the nomination to Charles Evan Hughes which caused the party to be entirely dissolved.
But I say, today, we bring it back! TR knew we needed bank reform, he knew we needed healthcare reform, and he knew the constitution needed to protect those it wasn't protecting!
And that's why I've changed my political views on Facebook to Bull Moose Party.
