Damn, you're good!
No person, (except a natural born citizen), (or a citizen of the United States at the time of the adoption of this Constitution), shall be eligible to the office of President
If I am understanding this correctly, a Natural born citizen, is a person who was born on U.S. soil by parents who both were born on U.S. soil.
A U.S. citizen who was born on U.S. soil but one of his parents was born in another country could have become President only during the time that the Constitution was being adopted. After the Constitution was adopted, this person would not be qulified. And the reason he would not qualify is 1) He doesn’t fall under the definition of a Natural Born citizen and 2). He was not a U.S. citizen during the period when the Constitution was being adopted.
Is this correct?
