Your Post #144: Good point.
It is very significant that no one prior to the fall of 2008 ever made the argument that it is absolutely necessary to have two citizen parents in order to qualify for natural born status. That's why no one objected to the candiacy of Sipro Agnew, Chester Arther, and others.
The 14th Amendment makes crystal clear that being born in the USA and being under US jurisdiction at the time of birth are sufficient.
The ficticious two-citizen parent requirement was literally made up out of whole cloth by birthers when their Kenyan birth myth failed to gain any traction.
