Let’s say a guy was born in Sheboygan to an American mother , and she doesn’t know who the father was as she slept with 20 guys and didn’t even get most of their names. Could be the father wasn’t a citizen. So is this guy of undetermined paternity a “natural born citizen”? :)
If I understand it correctly, the underlying meaning of the notion of natural born citizen is that the citizen has no foreign allegiances at birth. If the father is unknown at birth, then there would be no foreign allegiances from the father’s side at birth. The child would seemingly be unduly precluded from the presidency if the father were indeed a citizen, and unnecessarily precluded if the father were unknown as a father who is not legally recognized as such would have no legal claim to being responsible for the upbringing of the child. I am not a lawyer, etc.
