Progressive Party - nicknamed the "Bull Moose" Party, led by Theodore Roosevelt. The nickname came from Roosevelt's frequently-uttered statement that he felt "as strong as a bull moose." The party stood for lower tariffs, conservation policies, government regulation of big business, women's right to vote; an eight-hour work day; and the prohibition of child labor. In 1912, Roosevelt ran for President as a Progressive Party candidate. Although he lost the election, he was able to garner 27.4% of the popular vote, making him the most successful third-party candidate in American history.
