What the sheriff said (”the people who you think are his parents, aren’t”)
Means that any child of 0 Sr and SADO is NOT who is currently occupying the White House.
Also could mean that SAD and the kenyan were not the parents of any child. There was always Anna. The people in the village knew about Anna. Mary (she says) babysat for Anna when her own daughter, who was born in July 1959, was eighteen months old, remember? Have you asked yourself what you get when you add 18 months to July 1959? Charlette Le Fevre did, and she came up with 'early 1962' and no one noticed.
