Yes I am saying Its FMD. Partly because of FMD’s “Sex Rebel: Black” book and FMD’s extensive CP USA background.
CP USA in the 30’s was involved to a degree in recruiting leftists for infiltration work into the US Gov and agencies on behalf of the GRU/NKVD/KGB.
Don't disregard the fact of those nude photographs of Stanley Ann Dunham (Yes it's her, look at the crooked front tooth) taken in Frank Davis' home in December of 1960. (During the time she was already pregnant, and posing for Frank.)
There were three floating around, but there is a guy who created a video exploring this issue who claims to have found four more photographs of her taken in the same house. (He puts two of them in the trailer for his video.)
I'm of the opinion that Nude Stanley Ann around Christmas of 1960 means the photographer is the daddy. I don't think her Muslim boyfriend would have approved of her showing the goods or celebrating Christmas with Frank. Ergo, he didn't know about it.
