Or of an American child who aspires to the Presidency, and can think of no sound reason it should be denied to her.
Do you have a good reason?
Yes, I do. The Founding Fathers, the Supreme Court, and historians have spoken and written at length about the inherent dangers of dual nationality. When a U.S. citzen with dual citizenship is abroad in his or her country of birth, he or she has legal obligations to that country and that country has a predominant claim to him or her.
So, while China may not recognize the Chinese citizenship of a child adopted by Americans, other countries do. The inherent dangers of having an American POTUS who has duties and obligations to a foreign country as its citizen while within its borders is obvious.
That this child feels American or is raised as an American is irrelevant. The NBC claused was enacted to prevent foreign designs on the presidency. There should be no exceptions made for Chinese-born children adopted by Americans.
