1912 Republican National Convention

The 1912 Republican National Convention was held at the Chicago Coliseum, Chicago, Illinois, from June 18 to June 22, 1912. The party nominated President William Howard Taft and Vice President James S. Sherman for re-election for the 1912 United States presidential election.

Sherman died days before the election, and was replaced as Republican vice-presidential nominee by Nicholas Murray Butler of New York. The ticket went on to place 3rd in the November election behind former president Theodore Roosevelt, who ran under the banner of the new Progressive or "Bull Moose" Party, and Democratic Governor Woodrow Wilson.

Background
This convention marked the climax of a split in the party, resulting from a power struggle between incumbent Taft and former president Theodore Roosevelt that started in 1910. Politically liberal states for the first time were holding Republican primaries. Though Roosevelt had endorsed Taft as his successor, Taft's drift to the right had alienated Roosevelt, who launched a challenge to Taft's re-nomination. Roosevelt overwhelmingly won the primaries — winning 9 out of 13 states. Both Taft and Roosevelt lost their home states to each other. Senator Robert M. La Follette, a reformer, won two states, including his home state of Wisconsin. Through the primaries, Senator La Follette won a total of 36 delegates; President Taft won 48 delegates; and Roosevelt won 278 delegates. However 36 more conservative states did not hold primaries, but instead selected delegates via state conventions. For years Roosevelt had tried to attract Southern white Democrats to the Republican Party, and he tried to win delegates there in 1912. However Taft had the support of black Republicans in the South, and defeated Roosevelt there.

Convention
Entering the convention, the Roosevelt and Taft forces seemed evenly matched, and a compromise candidate seemed possible. Taft was willing to compromise with Missouri Governor Herbert S. Hadley as presidential nominee; Roosevelt said no.

The Taft and Roosevelt camps engaged in a fight for the delegations of various states, with Taft emerging victorious, and Roosevelt claiming that several delegations were fraudulently seated because of the machinations of conservative party leaders including William Barnes Jr. and Boies Penrose. Roosevelt then accused Taft of steamroller tactics and ordered his supporters to take no further part in the convention. Following the seating of the anti-Roosevelt delegations, California Governor Hiram Johnson proclaimed that progressives would form a new party to nominate Roosevelt. Roosevelt ultimately ran a third party campaign as part of the Progressive Party (nicknamed the "Bull Moose Party"). Taft and Roosevelt both lost the 1912 election to the Democratic nominee, Woodrow Wilson.
