Adams took charge of the Eisenhower campaign in the New Hampshire primary, winning all the delegates to the national convention. He campaigned for Eisenhower across the country, was Eisenhower's floor leader at the convention in battling against Senator Robert A. Taft, and impressed Eisenhower with his hard work, mastery of detail, and skill in political maneuvering. He became the campaign manager for the 1952 presidential campaign, where he was always at Eisenhower's side. He was the obvious choice for White House Chief of Staff--and was the first person in this position to hold the explicit title of "Chief of Staff," which Eisenhower had copied from military practice.
