Truman Defies Odds: Upset Victory in 1948 Election

Harry Truman defeated Thomas Dewey on November 2, 1948, in the greatest upset in American presidential election history. Every major poll predicted a Dewey victory. The Chicago Daily Tribune printed 'Dewey Defeats Truman' on its front page before the votes were counted. Truman won 303 electoral votes to Dewey's 189. The key was a 30,000-mile whistle-stop campaign in which Truman gave over 300 speeches from the back of his train, attacking the Republican 'do-nothing Congress.' Dewey ran a cautious, front-runner campaign and never engaged Truman directly. The pollsters had stopped sampling weeks before the election, missing a late shift among undecided voters. The photograph of Truman grinning while holding up the erroneous Tribune headline became one of the most famous images in American political history.
