Zero looks exactly (well a bit lighter) his half-brother in Africa. Google him (the brother is dead broke in some shanty).

I don’t buy the different dad theory.

Something else in there that’s worth hiding (assuming it exists).

I don't see any familial resemblance to the Obama clan. Plus, he shows absolutely no loyalty whatsoever to them ( the aunt, the brother, etc.).

Frank Davis, on the other hand, his son writes for OFA. If FMD is "Pop", that makes Mark Davis his half-brother.

There's an easy way to dispense of all this mystery. Release the damn birth certificate. If there's nothing to hide, there's no reason not to do it.
