Stassen's home-state delegation played a key role in the 1952 Republican contest when, over his objection, his delegates were released to Dwight D. Eisenhower. This swing helped Eisenhower to defeat Robert A. Taft on the first ballot. He served in the Eisenhower Administration, filling posts including director of the Mutual Security Administration (foreign aid) and Special Assistant to the President for Disarmament. During this period, he held cabinet rank and led a quixotic effort (perhaps covertly encouraged by Eisenhower, who had reservations about Richard Nixon's maturity for the presidency) to "dump Nixon" at the 1956 Republican Convention.
