According to some historians, Barack Obama won't be the first American president with African ancestry. As many as six previous presidents may have had black ancestors, with Warren Harding and Dwight Eisenhower being the most likely. None of the others claimed their heritage, however, choosing instead to pass as pure white. Obama is the first to acknowledge his bloodline.
