Gen. George Washington says goodbye to his troops, cheerleading is born, the "Spruce Goose" takes off, Truman defeats Dewey, and a federal holiday is created to honor Martin Luther King Jr., all on this day.
1948: Incumbent U.S. President Harry S. Truman defeats New York Gov. Thomas E. Dewey for re-election in one of the greatest election upsets in American history. The Chicago Tribune would publish an early edition with the now infamous headline "Dewey Defeats Truman." Truman won the electoral vote by a 303-189 majority over Dewey and Dixiecrat candidate Strom Thurmond, though a swing of just a few thousand votes in Ohio, Illinois and California would have produced the predicted Dewey victory.
