Truman was the sitting democratic president who upset Republican Thomas Dewey. Dewey was predicted to win because the Democratic Party was split but the voting gods saw otherwise.
"Dewey Defeats Truman" was an incorrect banner headline on the front page of the Chicago Daily Tribune on November 3, 1948, the day after incumbent United States President Harry S. Truman won an upset victory over Republican challenger and Governor of New York Thomas E. Dewey in the 1948 presidential election.
