David Pietrusza recounts the presidential campaign and election of 1948 that pitted Democratic President Harry Truman against Republican challenger Governor Thomas Dewey. The author examines the path that both nominees took to the election and the surprising upset, personified by the iconic photograph of Truman holding up a copy of the ChicagoTribune with the headline “Dewey Defeats Truman.” David Pietrusza responded to questions from members of the audience at the Clifton Park-Halfmoon Public Library in Clifton Park, New York.
