There is no divided allegiance if Rubio never had the citizenship.
“There is no divided allegiance if Rubio never had the citizenship.”
Marco Rubio was born with an inherent duty of obedience and allegiance to his father and his mother, both of whom were aliens in the United States owing a permanent obligation of allegiance and obedience to sovereign Cuba. That duty of obedience and allegiance to any foreign person or sovereign constitutes a divided obligation for obedience and allegiance other than the United States and its citizens.
Michelle Bachmann had the same problem, because she was born as a natural born citizen of the United States with two U.S. citizen parents. However, she subsequently married a husband who is a Swiss citizen, and she acquired Swiss citizenship and a Swiss passport. Although current U.S. law and practice is to not compel her to forfeit her U.S. citizenship since the Cable Act, she has nonetheless acquired a divided obligation of obedience and allegiance to her foreign husband and the foreign nation of Switzerland that has invalidate the sole allegiance of her former natural born citizenship.
