Cruz is a Natural Born Citizen according to current constitutional standards. Many people WANT it to mean that it requires 2 US Citizen Parents at birth, but as of right now, there is no Constitutional requirement for such a thing.
For those still pushing their opinions as constitutional, please pay attention:
Please provide the relevant sections of the U.S. Constitution that clearly and unambiguously define "Natural Born" as requiring two U.S. Citizens at birth.
Lacking that, Please provide the relevant sections of U.S. Federal Law that clearly and unambiguously define "Natural Born" as requiring two U.S. Citizens at birth.
Lacking that, Please provide the relevant rulings of the U.S. Supreme Court that clearly and unambiguously define "Natural Born" as requiring two U.S. Citizens at birth.
You won't because you can't because they don't exist anywhere except in your mind and in sources that are not legal or constitutional in nature.
CRUZ or LOSE!
The relevant section of the Constitution is Article 2, Section 1. This might also be of interest:
The Conclusive Definition Of “Natural-Born Citizen”
Natural-born citizens of the United States are those who are citizens of the United States from birth without having to perform any act to acquire or perfect their American citizenship. These are those whose parents are citizens of the United States at the time of their birth. Natural-born American citizens are those born of American citizen parents, within or without the American Republic, provided in the latter case that one of the parents had resided in the United States prior to the birth of the child. Their American citizenship is natural, the result of parentage, and not artificial or acquired by compliance with legislative provisions. A natural-born citizen is one not made by law or otherwise, but born. And this class is the large majority, in fact, the mass of our citizens; all others are exceptions specially provided for by law. A natural-born citizen is defined as one whose citizenship is established by the jurisdiction which the United States already has over the parents of the child, not what is thereafter acquired by choice of residence in this country. It is not necessary that a man should be born in this country, to be “a natural born citizen.” It is only requisite he should be a citizen by birth, and that is the case with all the children of citizens who have ever resided in this country, though born in a foreign country. Natural-born citizens, as distinguished from aliens and naturalized citizens, are those born in the United States of parents who are citizens. Natural-born citizens are also those born outside the United States and its outlying possessions of parents both of whom are citizens of the United States and one of whom has had a residence in the United States or one of its outlying possessions prior to the birth of the child. Hence, a child born abroad to two US citizen parents is a natural-born citizen: Provided, That at least one citizen parent had previously resided in the United States or one of its outlying possessions. U.S. Code: Title 8, 1401.
