WALTER E. WASHINGTON
(1915-2003)
Been looking to see when the earliest possible full African-American president could have been with a POD that is in the 20th century. Came across this man, who was the first Mayor of DC, and was really popular amongst his peers. He was the leader of Washington (how well named) when the riots appeared after the assassination of Martin Luther King Jr.
He did go to the 1976 Democratic Primaries... with these results:
Walter Washington - 5,161 (0.03%)
