The Republican Party is one of the two main political parties of the United States (the other one is the Democratic Party).

In 1908, Theodore Roosevelt handpicked William Howard Taft as his successor, but they became enemies as the party split down the middle. Taft ended up defeating Roosevelt for the 1912 nomination, and Roosevelt ran with the new Progressive Party. When he lost, most of his supporters went back to the Republican Party, only to find out that they did not agree with the economic thinking of Taft, which lead to the ideological change of the Republican Party.
