During his two terms as vice president, Nixon campaigned actively for Republican candidates but otherwise did not assume significant responsibilities. (Asked at a press conference to describe Nixon’s contributions to his administration’s policies, Eisenhower replied: “If you give me a week, I might think of one.”) Nevertheless, his performance in office helped to make the role of vice president more prominent and to enhance its constitutional importance. In 1955–57 Eisenhower suffered a series of serious illnesses, including a heart attack, an attack of ileitis, and a stroke.
