Showing our forefathers meant by "naturally born", it was if the father was a citizen. The child's citizenship was based on the father, not the mother.

This woman lost her citizenship due to marriage of a non citizen, in Hawaii.
Notice this phrase there, "Historically, wives belonged with husbands, husbands to the nation".
Also; "Before the Cable Act and it's amendments, the Citizenship status of minor children and wives was folded within that of fathers and husbands, uniting the family undeer a single civic identity. While both naturalizatioin and immigration policies privileged family unity, they also defined the legal parameters of "family" and regulated the implications of inherited status. "
We have abandoned the "natural" condition of citizenship by husband and/or fathers unfortunately in 1934 when the unconstitutional 1934 Equal Nationality Act, which also allowed women to pass citizenship on to their children. So, follow the unconstitutional understanding, or the Constitutional understanding. The ONLY way that should and could be changed and made valid would be by Amendment.
So, under Constitutional understanding, if we had honest Supreme Court Judges and honest politicians, Obama is and remains a citizen of Kenya, through is father, and NOT a "natural born" citizen of the USA, rather he could become a "naturalized citizen" but still not Constitutionally eligible to be President.
From that foolish and errant law, we now also have the scourge of "anchor babies" complicating matters for immigration officials.
