1944 Democratic National Convention

Despite the obvious physical decline in the President's appearance, as well as rumors of secret health problems, Roosevelt's fourth nomination as President was largely unchallenged. The contention lay in the vice-presidential nomination. Henry Wallace had been elected Vice President in 1940. He was FDR's preferred choice and was very popular with rank and file Democratic voters. However, conservative Party leaders, such as James F. Byrnes, strongly opposed his renomination. They regarded Wallace as being too far to the left, too "progressive" and too friendly to labor to be next in line for the Presidency. Outgoing Democratic National Committee chairman Frank C. Walker, incoming chairman Robert E. Hannegan, party treasurer Edwin W. Pauley, strategist Edward J. Flynn, Chicago Mayor Edward Joseph Kelly and lobbyist George E. Allen all wanted to keep Wallace off the ticket. Their group was deemed by Allen as "The Conspiracy of the Pure in Heart."[5] They privately told Roosevelt that they would fight Wallace's renomination, and they proposed Missouri Senator Harry S. Truman as FDR's new running mate. Truman had entered the Senate in January 1935 with a reputation as "the senator from Pendergast". Then he had become well known during the war as the chairman of a Senate investigating committee. Roosevelt personally liked Wallace and knew little about Truman, but he reluctantly agreed to accept Truman as his new running mate to preserve party unity.

President Roosevelt traveled to the South Pacific in order to discuss military strategy with General Douglas MacArthur, and thus didn't attend the convention. This was the last time that a presidential nominee failed to attend a national convention during the 20th century. Even so, many delegates refused to abandon Wallace. In the first ballot, Wallace led with 429.5 votes and Truman got 319.5 votes. But Wallace was 159.5 votes short of a majority. The party leaders went to work talking to delegates, cutting deals and applying pressure to persuade them to select Truman. Truman won the second ballot by 1031 votes to 105. The maneuverings over the 1944 vice presidential nomination proved to be historic, as FDR died in April 1945, and Truman, not Wallace, thus became the nation's 33rd President.[6]

Senator Samuel D. Jackson, who had worked feverishly to secure Truman's nomination, later said he wanted his tombstone inscribed with the words "Here lies the man who stopped Henry Wallace from becoming President of the United States."[7]
