Few people believed that President Harry S. Truman had a chance of winning the 1948 presidential election. The three great national polling organizations all predicted that Governor Thomas E. Dewey of New York, his Republican opponent, would win by a wide margin. The press was equally certain of a Dewey victory, for the odds against the incumbent seemed insurmountable. Truman's own party had split, with Democrat Strom Thurmond running in the South as a 'Dixiecrat' and former vice president Henry Wallace running as the candidate of the newly formed Progressive Party. It was expected that Wallace would drain vitally needed liberal votes away from the president. Among Democratic politicians and his own campaign staff, it seemed that the only person who thought Truman could win was the candidate himself.
