You must be born on US soil, to at least one American citizen, to be natural born. At the time John McCain was born in the Panama Canal Zone to Navy parents, the zone was US territory, hence he is a natural born citizen.chrismb wrote:Can you clarify for my lowly misunderstandings of the American constitution - I was under the impression that the current right to stand for Presidency of the US is based on whether you were an American Citizen at birth, and jus sanguinis ('right of blood') means that you need not be born on US soil to qualify, provided, of course, you have an American parent? Citizenship is not something you need to 'apply' for, for example - if any such applications need be made then they are merely applications for the issue of documents to provide documentation on said citizenship.
So, to my understanding, if Obama was born on the planet Mars, so long as at least one of his parents was American at the time then he's 'qualified' to be POTUS.
The only cases for non-qualification for jus soli in this regard are if you were on US soil for some limited classes of exceptions, e.g. one is if you were born to non-US diplomats who were resident in the US at the time.
Kenya has never been US territory. If Obama had been born at the US Embassy in Kenya, then he would be natural born. Thats about the only way he could be qualified, assuming his grandmother was telling the truth that he was born in Kenya.
One amusing historical note, Martin Van Buren, who spoke dutch as his native language, was the first president actually born in the US, the previous presidents were born in the colonies before the revolution. Despite this, there is common belief that he was some sort of 'foreign' president because he spoke english only as a second language. He was from New York, from a very Dutch farming area.
