“If Barack’s mom is a U.S. citizen, and if he was born in Hawaii, then he is “natural born.””
True enough, but if he were not born in Hawaii then he may not be a “natural born” citizen.
A natural born citizen would have 2 parents of the same nationality as per William Blackstone, Commentaries of 1765.
True enough...
I'm afraid that it's NOT "true enough".
Obama cannot be a Natural Born Citizen of the US because his father was a citizen of Kenya. The very best that Barack Obama can qualify for, is simple US citizenship. Not Natural Born citizenship, as understood by the Framers of the US Constitution.
