On June 11, 1963, John F. Kennedy issued a presidential spanking of Alabama Gov. George Wallace, a proud racist who refused to allow black students to register at the University of Alabama. Kennedy threatened Wallace with arrest by the National Guard — a bold and risky move, to be sure — if he didn't comply. The politician in Wallace made him eat his pride and step aside. But 50 years later, the university is still cleaning the stains of white supremacy from their walls.
