Natural born citizen means born here of citizen parents.
The founders wanted no foreign influences on the Presidency.
If one could be anything other than a US citizen at birth, one cannot be a natural born citizen.
Cruz was Cuban, Canadian and US citizen at birth
Rubio was US and Cuban
Neither is eligible
Owebowmao was a British subject and US citizen
He is ineligible as well
And there is influence if your are foreign born. I have lived in this country since the age of 11, I am a naturalized citizen, but I still defend my country of birth if anyone makes derogatory comments. I’m a loyal American, vote in every election, do my homework about the candidates and issues, have always held a job until retirement, and never had to rely on social services for help. but I still feel affection for my country of birth. I attended citizenship classes before achieving citizenship, and know I could never run for President or V.P., the highest offices in the land.
I always find it funny when people claim they knew the founders wanted no foreign influences. The founders did not want a women to be president either. The founders did not think blacks were human.
But to your point, a lot of constitutional scholars believe the Natural Born Clause was added to make eligible American Citizens born aboard. Just the opposite of the prevailing thought.
Personally I believe that Cruz is eligible and your opinion might be different. So, we agree to disagree.
All of these Presidents were born under foreign influences (until 1841).
