Yes, he was.
But Obama was born to an American mother on American soil.
That being the case, he is clearly a US natural born citizen.
Doesn't matter whether you like it. Doesn't matter whether I like it. Doesn't make him a good President. He's frankly a sorry-@$$ President. It just means he was legally elected. And whether you or I like it, that's the way it is.
Because unlike you, I recognize what the law is, whether I like it or not.
In 1787 they didn't have split citizenship. Marriage to the father naturalized the mother. Parents were always the same citizenship until 1922.
Now you can say the law was sexist, and it was, but the point still remains that there was NO SUCH THING AS DIVIDED CITIZENSHIP in 1787.
Congress created this Bastard class by passing a well meaning law in 1922, and reinforced it in 1934. But it is not a "natural" form of citizenship. It's bizarre and prone towards abuse, as Obama has so aptly illustrated.
Because unlike you, I recognize what the law is, whether I like it or not.
Naw, you just repeat what people tell you when you agree with it.
