I posted Mary McManaman’s article here the day she wrote it. I agree. It provides a very clear explanation.

If Ted Cruz is not eligible the good news is that Rubio is a sure bet to not be

If Ted Cruz bounces Rubio he’ll have done a great service to the country

From your link:
The Constitution provides that 'No person except a natural born Citizen . . . shall be eligible to the Office of President.' The concept of 'natural born' comes from common law, and it is that law the Supreme Court has said we must turn to for the concepts definition. On this subject, common law is clear and unambiguous. The 18th-century English jurist William Blackstone, the preeminent authority on it, declared natural-born citizens are 'such as are born within the dominions of the crown of England,' while aliens are “such as are born out of it.' The key to this division is the assumption of allegiance to ones country of birth. The Americans who drafted the Constitution adopted this principle for the United States. James Madison, known as the 'father of the Constitution,' stated, 'It is an established maxim that birth is a criterion of allegiance. . . . [And] place is the most certain criterion; it is what applies in the United States.”

-It is an established maxim that birth is a criterion of allegiance-. . . .

Read that again really slow so the words and what they mean slosh around your brain...

The intent of Madison maxim was the issue of allegiance...

In Madison time allegiance WAS an important and serious issue, considering Great Britain attacked America in 1812 again to try and seize her back to the throne...

Is there any doubt or evidence what country Cruz has allegiance to?

The idea that some foreign born entity will somehow get elected POTUS is really a strawman argument, whoever runs for POTUS needs to win over the american people to be the nominee...

I doubt some Syrian refugee plopped over here by Obama will be able to run the table and be POTUS
