I don’t think Cruz’ eligibility matters anymore. For them to bring up the question now will bring up the same question about oblunder. The line has been crossed with no repercussions.
For Cruz to be disqualified opens the argument about what constitutes a “ natural born citizen”. Even if you take the phrase at face value to mean that a person should be born to American born parents on American soil then even oblunders phony birth certificate disqaulifies him.
Actually, I don't think that's the face value definition. That's a learned definition, which is known to people who went deep into the Obama birth controversy.
I think the face value is "citizen at birth". This is how we think about things day-to-day: either you naturalized or were a born citizen. We all know that Schwarzenegger is naturalized. Cruz was a citizen at birth, via his American mother. Same as Obama.
Birthers never managed to get many people to agree with their main idea that "natural born" has multiple requirements and is not synonymous with "Citizen at birth".
I'm not passing judgement on their claims, and whether Obama was even a citizen at birth is hard to know, given that the documents he provided were obviously forged.
What I am describing what I believe the view of most Americans is. if you were a citizen at birth you are eligible. If you are an immigrant, you are not.
