That article you referenced is fine and generally makes sense to me (and is how I have always viewed it) but I was specifically trying to understand your stance on "natural born" citizenship as a component of "Natural Law", and I couldn't make the connection. (This is distinct from the term "Naturalized Citizen" which is the process by which a foreigner becomes an American citizen. I dislike that term, and think it is to easily confused with "natural born".)
I don't understand why people had an issue with McCain's "citizenship". I came through the first decade of this century with an increasing distaste, then dislike, and finally, open and unmitigated detestation of him. I had personal reasons for taking that long to view him in that light, but I eventually did.
That said, there is plenty of ground to despise him, but I have never, ever thought his citizenship was in question.
Both his mother and father were American citizens, there is no question about that. That he was born overseas is of no consequence to me. I grew up in a military family and travelled all over the world, and saw pregnant women who were wives of military personnel giving birth on bases overseas. If my mother had been pregnant and given birth to me overseas, is someone going to say I am not an American citizen, or ineligible to run for President? Of course not.
What if a pregnant American citizen married to another American citizen was visiting relatives just over the border in Canada and gave birth prematurely? I don't think that means her child is not a naturalized citizen.
In that light, I fully recognize and accept that a child born to two American Citizens whose allegiance to the United States is not in question that is born anywhere in the world is a full American citizen up to an including running for President of the United States. To say otherwise requires complicated and messy bureaucracy and red tape to take into account diplomatic or military personnel, Americans traveling abroad, etc.
However, I am fully and unequivocally onboard on four specific items:
To be naturally an American one must be both Jus Soli and Jus Sangiune.
Soil and blood.
McCain was chosen as the Designated Loser for the Kenyanesian Usurper specifically because his case would elicit sympathetic responses.
Everyone knows his father was an Admiral in the US Navy and was then stationed in Panama.
McCain was born in the country of Panama, not the Canal Zone, which at the time was US soil.
He refused to release his birth certificate because that would be revealed.
Children born to US citizens abroad are US citizens, but they are not natural born citizens.
That is made clear by reading the 1790 Naturalization Act where they say children born to citizens parents overseas shall be regarded as natural born citizens, clearly indicating they are not, that act was repealed 5 years later with that language removed when they realized their error.

Every tab in the sidebar is a separate article.
Until the 1960s the military would tell expectant mothers to return home to give birth to preserve natural born citizen status. It only matters for President. (and it matters ALOT as we found out)
My friend who was born in Germany 1960 (his father US Air Force there) and was told he was a US citizen but not a natural born citizen eligible to be President.
