President Harry Truman jubilantly holds up a Chicago newspaper emblazoned with the (erroneous) headline, DEWEY DEFEATS TRUMAN. In fact, Truman handily beat New York governor Thomas Dewey in the tight 1948 presidential election.

The United States presidential election of 1948 was the greatest election upset in American history. Virtually every prediction (with or without public opinion polls) indicated that incumbent President Harry S. Truman would be defeated by Republican Thomas E. Dewey.

For the past couple of years, they had been confident Barack Obama would lose in November. Many Republicans held that belief going into Election Day.

The Republican psyche will take a while to recover from the shock of November 6.
