Answer and Explanation: Truman chose not to run for president in 1952, and Adlai Stevenson, the governor of Illinois, was the Democratic candidate for president.
This question makes it seem like Truman fully ran for the nomination. Harry Truman ran but withdrew after a New Hampshire primary loss to Senator Kefauver.
Ultimately, Adlai Stevenson was the Democratic nominee in 1952 and would lose to Dwight Eisenhower.
