The founders excluded the children of foreign nationals with the natural born citizen clause.
By definition those born with multiple nationalities are NOT NATURALLY Americans.
The example of the Kenyanesian Usurpation should be a clear enough example that they were right to anyone.
Yet we still have people even here on FR arguing that children born to one American parent in a foreign country are eligible to be President.
Anwar Al-Awlaki’s kids born in Yemen are just as eligible to be President as Ted Cruz.
For an example of citizenship by birth to a U.S. citizen, presidential candidate Ted Cruz (running in 2016) was born in Canada to a citizen mother and a non-citizen father. Under the version of the naturalization statute in effect at the time, Ted was a citizen at birth provided that his mother had been physically present in the United States for 10 years before Ted’s birth, and at least 5 years before she turned 18. There’s no particular reason to doubt that Ted’s mother satisfied these physical presence requirements, so Ted is almost certainly a citizen from birth.
Likewise, presidential candidate George Romney (ran in 1968) was born in Mexico to two U.S. citizens. I have never researched in detail the citizenship law that existed in 1907, but my understanding is that he was a citizen from birth by virtue of his parents’ citizenship.
