If a child is born a Citizen of the United States and meets the other qualifications of age and residency, then he is eligible to be elected to the Office of the President of the United States.
Period.
Now take your silly hypothetical to another forum.
What is so silly about the hypothetical?
Didn't a British sovereign once marry a divorced American citizen and abdicate? Had he not abdicated and instead given birth to an heir, would that heir be eligible or not?
Are you unable to answer the question?
If that were the case, the Founders would not have bothered to change the original proposed presidential eligibility requirement of 'born a Citizen' to 'natural born Citizen'.
Natural law is clear about who is a natural born Citizen - those born in the country to Citizen parents.
