The United States presidential election of 1944 took place while the United States was preoccupied with fighting World War II. President Franklin D. Roosevelt (FDR) had been in office longer than any other president, but remained popular. Unlike 1940, there was little doubt that Roosevelt would run for another term as the Democratic candidate. His Republican opponent in 1944 was New York Governor Thomas E. Dewey. Dewey ran an energetic campaign, but there was little doubt, in the midst of a world war, that FDR would win a record fourth term.
