Well, the problem is the “citizen at birth” provision in 8 USC Section 1401. I believe scholars and pundits are interpreting “citizen at birth” to be the same as “natural born citizen.”
Actually, I am hoping this matter ends up before SCOTUS so it can be settled. However, knowing our learned justices, they will probably punt. Bunch of corrupt cowards.
This does need to be adjudicated by SCOTUS. We are fast approaching the highest ratio of immigrants to native born in our history. In 1970 one in 21 was foreign-born; today it is less than one in 8, the highest in 105 years; and within a decade it will be one in 7, the highest in our history.
Natural born citizen is a subset of citizen. The only place it comes into play is Art. I Sec II. eligibilty for President. A natural born citizen is one who can be no other. Born here of citizens and needs no statutory citation.
They intended to insure that there would be no foreign influence. No divided loyalties. If you can be some other citizen at birth, by geography or parentage, you cannot be a natural born citizen.
