Harry S Truman became President because of the death of Roosevelt. He served most of Roosevelt's last term as President. This would have limited him to being elected only one time, but he was not affected since the amendment did not affect the person who was the current President when the amendment was originally proposed by Congress. Since this provision could only have applied to Truman, it was an obvious effort not to limit him. Truman did win the election in 1948 but ended his try to be President in 1952 before the election began.
