In the case of the Mittster, all 50 states and DC put him on the ballot in 2012 in the general election; plus, he appeared on the primary ballot in all states holding Republican primaries in 2008 and 2012. So, opinion among those having a say in the matter was unanimous: he was “natural born.”
As I stated in Post 114, “Under U.S. law, overseas nationals who do not revive their citizenship can only pass citizenship to the next generation.” This means of course that the Mittster did NOT inherit natural-born U.S. citizenship from his grandparents. So, how was he a natural-born U.S. citizen:
#1 His father, George Romney (who was the 4th person I had in a list in Post 112), “returned” to the U.S. and thus revived the lineage.
#2 His mother, Lenore Romney, was born in the U.S.
#3 He himself was born in the U.S.
George Romney was born in Mexico and was ineligible.
