In one of the greatest upsets in presidential election history,
Democratic incumbent Harry S. Truman defeated his Republican challenger, Governor Thomas E. Dewey of New York, by just
over two million popular votes. In the days preceding the vote,
political analysts and polls were so behind Dewey that on
election night, long before all the votes were counted, the
Chicago Tribune published an early edition with the banner
headline “DEWEY DEFEATS TRUMAN”(above).
