A person can be either a) a naturalized citizen or b) a citizen at birth who does not require naturalization. There is no in-between. Cruz is the latter.

The controversy centers at/in the Constitution which/where specifically by 1st and 2nd Articles there is a specific delineation in wording between ‘citizen’ and ‘natural born citizen’. For years politicians have used obfuscation to circumvent the difference in wording. The first successful one I know of was when Arthur who had a questionable US birthright succeeded McKinley who was assassinated. The second successful one I know of is Obama who had his path cleared by Pelosi vouching for Obama’s qualifications for POTUSA. It is my understanding that Obama was sired by a SE Asian guru named Muhammed Subuh with a young filly not yet 18 years of age named Stanley Ann Dunham. I don’t believe that eligibility for POTUSA is as Constitutionally as simple as just an either or situation as many others take the matter.
