Harry S. Truman
Presidency (1945–1953)
In 1951, the United States ratified the 22nd Amendment, making a president ineligible for election to a third term or for election to a second full term after serving more than two remaining years of a term of a previously elected president. The latter clause would have applied to Truman's situation in 1952 were it not for a grandfather clause excluding the amendment's application to the incumbent president.
