Twenty-second Amendment to the United States Constitution
Richard M. Nixon became the second person not allowed to run again for President when he won the elections in 1968 and 1972, but he was forced to resign due to the Watergate scandal 19 months into his second term. Gerald Ford became President in 1974 after Nixon left office. Ford served the last 29 months of Nixon's term. This meant he could only be elected as president once, but he lost the election to Jimmy Carter in 1976 and did not try to become President again.
