President-elect of the United States the 25th Amendment. The first instance was in 1973, when Gerald Ford was nominated by President Richard Nixon to succeed Spiro Agnew, who had resigned. The second came in 1974, when Ford, who had succeeded to the presidency following Nixon's resignation, nominated Nelson Rockefeller to succeed him. During both vacancies, the nominee was called Vice President-designate, instead of Vice President-elect, as neither had been elected to the office. As a result of these events, the nation has had two more Vice Presidents than it has had Vice President-elects. While he is currently the 48th U.S. Vice President, Mike Pence was
Vice President of the United States to have been elected president while not an incumbent, as well as the only person elected twice to both the presidency and vice presidency. Prior to ratification of the Twenty-fifth Amendment in 1967, no constitutional provision existed for filling an intra-term vacancy in the vice presidency. As a result, when one occurred, the office was left vacant until filled through the next ensuing election and inauguration. Between 1812 and 1967, the vice presidency was vacant on sixteen occasions—as a result of seven deaths, one resignation, and eight cases in which the vice president succeeded to the presidency.
