Thomas Edmund Dewey (March 24, 1902 – March 16, 1971) was the Governor of New York (1943-1955) and the unsuccessful Republican candidate for the U.S.Presidency in 1944 and 1948. As a leader of the liberal faction of the Republican party he fought the conservative faction led by Senator Robert Taft.
During the 1930s, Dewey made a name for himself as a fearless prosecutor, actively trying and convicting several key organized crime figures of New York City.
He is well remembered in popular culture for being incorrectly announced by the Chicago Tribune as the presidential winner in 1948, over Harry Truman, who then celebrated this reversal of fortune in an iconic photograph.
He did gain the GOP nod in 1944, running against incumbent Joe Steele, who was running for an unprecedented fourth term. While Dewey campaigned hard, promising to do better in the war and to do away with the labor camps Steele had established in the country, it was difficult to campaign substantively against Steele's successes: World War II was going absolutely in the Allies' favor, while at home, the economy was in great shape, with people now earning more than they had before Steele took office in 1933. People had generally come to accept the camps, and were indifferent to Dewey's call for their end. Moreover, Steele's apparatus was difficult to contend with. In the end, Steele trounced Dewey. In his concession speech, Dewey wished Steele well, because wishing the President well meant wishing the country well, and Dewey loved the U.S. as he knew Steele did as well.
Dewey is not mentioned in the short story, where Steele ran unopposed in 1944.
At his inauguration on February 1, 1945, Dewey pledged to continue U.S. occupation of the C.S. with the intent to integrate the southern states back into the U.S. He also pledged to continue La Follette's policy of racial equality in the armed services. Addressing the international stage, Dewey proposed a continued partnership with the U.S.'s traditional ally, Germany, to police the world and prevent the spread of superbomb technology to former enemies Russia, Japan, and France.
Harry Truman, the 33rd President of the United States in OTL. He ascended to the Presidency upon Roosevelt's death in 1945. Truman, a Democrat, defeated the Republican Dewey in the 1948 election (unlike the Southern Victory series, where Truman was Dewey's running mate on a Democratic ticket). Based on faulty polling data, the Chicago Tribune printed headlines proclaiming "Dewey Defeats Truman", which was echoed in the Southern Victory series.
