President Dwight D. Eisenhower was nonpartisan until 1952, when he joined the Republican Party and was elected president. According to David A. Crockett, "Much of Eisenhower's nonpartisan image was genuine, for he found Truman's campaigning distasteful and inappropriate, and he disliked the partisan aspects of campaigning." With little interest in routine partisanship, Eisenhower left much of the building and sustaining of the Republican Party to his vice president, Richard Nixon. With Eisenhower uninvolved in party building, Nixon became the de facto national GOP leader."
