I think a constitutional clarification or amendment is needed to cover those circumstances where a person was born to American parents overseas who both were there temporarily and had no plans to be ex-pat.

Here ya go-

§ 215. Children of citizens born in a foreign country.
It is asked whether the children born of citizens in a foreign country are citizens? The laws have decided this question in several countries, and their regulations must be followed.(59) By the law of nature alone, children follow the condition of their fathers, and enter into all their rights (§ 212); the place of birth produces no change in this particular, and cannot, of itself, furnish any reason for taking from a child what nature has given him; I say "of itself," for, civil or political laws may, for particular reasons, ordain otherwise. But I suppose that the father has not entirely quitted his country in order to settle elsewhere. If he has fixed his abode in a foreign country, he is become a member of another society, at least as a perpetual inhabitant; and his children will be members of it also.

It is not part of the US Constitution.

You realize that was written before the US even exisited and has no bearing or authority in US law.

Constitutional fixes in the here and now is what is needed...not some opinion from a book!

In 1790, Congress did just that. Read my post above where this is discussed.

And "temporarily and had no plans to be ex-pat" is irrelevant, since there are no restrictions based on length of time outside the borders. "Ex-pat" is a description of location. It doesn't necessarily have anything to do with political outlook. Someone may be ex-pat who is heading up a mine project or who is teaching at a foreign university or who is a disgruntled Hollywood prick trying to make a political statement.
