William Howard Taft
During Taft's presidency, his relationship with Roosevelt became bad, because Roosevelt thought Taft was not doing a good job and taking too little actions against so-called trusts. Taft was also more conservative and he did not continue all of Roosevelt's progressive policies. As a result, in 1912, Theodore Roosevelt came back into politics and ran for president against William Taft. Many Republicans split their votes between Taft and Roosevelt, and the Democratic opponent Woodrow Wilson won the election.
