On Tuesday, 7 November 1944, Franklin D. Roosevelt won his fourth term as President of the United States, defeating Republican Thomas E. Dewey of New York.

Few states in the 1944 election had a primary system in place to vote for party nominees, instead choosing delegates to the national nominating convention through party caucuses or state conventions. The real job of selecting the party’s nominees occurred at the national conventions with little to no input from the voting public.

Democrats, concerned that Roosevelt might not live to complete his term, replaced the sitting left-wing and economically illiterate Vice President Henry A. Wallace with the Missouri Senator Harry S. Truman.

Roosevelt died on 12 April 1945, less than three months into his new term, with Truman assuming the presidency that same day.

Truman ordered the dropping of the first atomic bomb on Hiroshima on August 6, 1945, less than six months into his presidency, proving that holding the highest office in the land is fraught with uncertainty and requires unimaginable determination and strength.
