I’ll agree that there are some unusual cases, such as yours. (And by the way, thanks for choosing life.) But the principle is a sound one, I think, namely that when both parents are not American citizens, there is the potential for the non-citizen parent to exert influence. Even if that parent were absentee, there could be influence at some later time.
But suppose someone in circumstances like yours does have a Dad who decides he wants to be involved in his son's life and takes said son back to Germany and raises him there. Would you then consider him natural born or want a non-American (having been raised in Germany) occupying the Oval Office???
I would reiterate that no one (including natural born citizens 10 generations long descending from revolutionary war veterans) have a RIGHT to be President. Its an honor, but it is not a right.
Our founders knew this and imposed strict restrictions knowing full well there would be the occasional exception and unusual cases such as yours. It doesn't change the fact that safeguards must be put in place to protect us from other unusual cases that would bring harm to the nation.
