The "CRS White Paper" to which you refer is likely the one authored by Jack Maskell on November 14, 2011, shortly after the 2011 9th Circuit Marguet-Pillado decision: http://www.fas.org/sgp/crs/misc/R42097.pdf You question obiter dicta from that decision. The 2011 CRS White Paper does not discuss a fact pattern where only one parent of a foreign-born presidential candidate was a citizen at the time of the candidate's birth.

The CRS opinion that the above article references was authored by CRS in 1967 concerning the eligibility of George Romney. The 1967 CRS opinion is alleged to state that such a foreign-born child of only one citizen would be "natural born".

Has this 1967 CRS opinion been debunked?

Has this 1967 CRS opinion been debunked?

This is the first time that it has popped up on the radar probably since 1967. The OBots didn't know about it until now or very very recently.

The 2011 CRS White Paper does not discuss a fact pattern where only one parent of a foreign-born presidential candidate was a citizen at the time of the candidate's birth.

Without even looking at it - it is highly likely ...99.9998% certainty that it is bunk.
