Answer:
the Progressive Party
Step-by-step explanation:
Having served as the President of the United States between 1901 to 1909, Theodore Roosevelt ensured that it was William Howard Taft, that succeeded him, in the hope that he will continue his political agenda.
However, during the Taft administration, he appeared to have deviated for Theodore's principles. This led Theodore Roosevelt to seek for third term Presidency again in 1912, but lost the Republican primary to Howard Taft. Following this development, he went ahead to create a new party known as the PROGRESSIVE PARTY.
