Unless he was a naturalized citizen it is. He was not naturalized, therefore a natural born citizen - there is no other (3rd) type.
Show me the naturalization paperwork and I’ll believe it’s a problem. ...except nobody can, because he was never naturalized.
Look, it is looking more and more as if Ted Cruz came to the United States illegally in 1974, and no paperwork was filed to establish his US Citizenship until 1986 (IIRC), and that was under the Naturalization Act in force at the time. He renounced his Canadian citizenship in 2014, after he was already serving in the United States Senate.
Now if Ted Cruz shows the paperwork that was filed in 1986 to allow him to get a US Passport, we can settle the matter of both his citizenship (yes) and whether he was a natural-born American (no). If he doesn’t show the paperwork, than this remains in legal limbo.
While you are correct that Cruz never needed to be naturalized, it’s not so simple.
1. We have no perfectly clear definition of natural born citizen and until we do, these issues will be fraught with argumentation.
2. He was not officially American until he was 16. Though he COULD have been, since birth, he wasn’t officially. That is bad optics for the presidency.
3. Ted Cruz knows 1 and 2, above. He has chosen not to address those two points honestly. That speaks directly to his character.

It further states that just because someone doesnt file for CoC, (form N-600) doesnt mean they arent a full citizen, it infact states that they do not have to go through a naturalization process
