The most successful third party in American History. It was headed by Tedd Roosevelt fresh of his African Safari and was completely based of his candidacy of the 1912 Presidental election. The whole purpose was to get rid of President Taft after TR realized that he sucked as a president. Bull Moose split the Republican vote and allowed Dem. Woodrow Wilson to win the election. The Party died with TR in 1919.
More states voted Bull Moose than voted Republican.
