If Barack Obamas real father was either Malcolm X or Frank Marshall Davis that would clarify that Obama is indeed a natural born citizen
But it might disqualify him from being called Barack Obama.
Also depends on nationality of mother and place of birth. If his father was MX and mother a foreigner, and born outside the US, he not only would not be a NBC, he wouldn’t be a citizen at all.
Just think!
Wait, MalCoX was a citizen.
