We will see. Have you checked out the sources and corroborative resources in:

...?
Some of them. I've read the relevant portions of "The Law Of Nations" and "Blackstone's Commentaries ". Still need to read Tucker, but one must always keep in mind that Tucker was writing *after* the Constitution had passed. Still he's generally considered authoritative on it's meanings.
Tucker gives a good explanation of the reason for requiring a President to be a natural born citizen, that is to avoid foreign influences. But, as Blackstone explains the term "natural born", that can be as well accomplished by someone with two US Citizen parents who happens to be born outside the country, particularly when one or both of them are in it's service at the time. (To include ambassadors, embassy staff, and military). Blackstone even extends that to a person born outside the realm (he's speaking of England of course) whose father is a subject/citizen of the realm.
But as you say, we will see, probably sooner rather than later. I hope the issue doesn't cast it's pall over the Christmas season, but I expect it will.
