Answer:
E. Theodore Roosevelt: William Howard Taft: Bull Moose Party
Step-by-step explanation:
The Progressive Party was a third party in the United States formed in 1912 by former president Theodore Roosevelt after he lost the presidential nomination of the Republican Party to his former protégé and conservative rival, incumbent president William Howard Taft.
The Progressive Party was popularly nicknamed the "Bull Moose Party" since Roosevelt often said that he felt "strong as a bull moose" both before and after an assassination attempt on the campaign trail. The party's platform built on Roosevelt's Square Deal domestic program and called for several progressive reforms.
