The Supreme Court in Minor made a distinction between citizen and natural born citizen.
Are you saying that a person born a dual citizen was acceptable to the Founders as a President? By what authority? What explains the revison to the eligibility requirements from the original draft which did not include the words “natural born”? Maybe John Jay and George Washington were being racists.
Which authority of yours says an anchor baby is eligible to be President of the United States? Other than the kid’s mother?
The United States does not recognize “dual citizenship” — and never has.
Your question is a moot point.
