Taft was elected president in 1908, the chosen successor of Theodore Roosevelt, but was defeated for re-election by Woodrow Wilson in 1912 after Roosevelt split the Republican vote by running as a third - party candidate. In 1921, President Warren G. Harding appointed Taft to be chief justice, a position in which he served until a month before his death.
