Truman had been a surprise choice for vice president at the Democratic Party nominating convention in nineteen forty-four. Delegates considered several other candidates before they chose him as Roosevelt's running mate. That was at a time when presidential candidates did not make their own choices for vice president.
Harry Truman lacked the fame, the rich family and the strong speech-making skills of Franklin Roosevelt. He was a much simpler man. He grew up in the Midwestern state of Missouri. Truman only studied through high school but took some nighttime law school classes. He worked for many years as a farmer and a small businessman, but without much success.
Truman had long been interested in politics. When he was almost forty, he finally won several low-level positions in his home state. By nineteen thirty-four, he was popular enough in Missouri to be nominated and elected to the United States Senate. And he won re-election six years later.
Most Americans, however, knew little about Harry Truman when he became president. They knew he had close ties to the Democratic Party political machine in his home state. But they had also heard that he was a very honest man. They could see that Truman had strongly supported President Roosevelt's New Deal programs. But they could not be sure what kind of president Truman would become.
