Not a stupid question at all. A constitutional requirement to be president is being a natural-born citizen. That's a higher threshold than just "citizen." Natural-born means born on US soil. US military bases and zones overseas are also considered US soil. Parents can confer citizenship to a child born overseas, but not the natural-born part. That's a function of geography. So my understanding of it is, it wouldn't matter if both parents were US citizens. If he was born in Kenya, he would not be a natural born citizen. The age of the mother is only an issue if he were born in Hawaii, as the automatic US citizenship that comes with being born on US soil has exceptions that fall in the date range that Batack was born.
Since it's never really been tested in the Supreme Court, I'm sure that everyone (meaning democrats) will want to just dismiss all that as antiquated technicality.
That is incorrect. Natural-born citizen means a citizen from birth, rather than through naturalization. As early as 1790, Congress passed a law clarifying that a child born to American citizens overseas is a natural born citizen. There are some twists that come in when a child is born overseas and only one of his parents is a citizen, but that is jus a question of whether or not a kid is a citizen at birth. That is, there is no such category of American who was a citizen at birth but does not qualify as a natural born citizen.
