The founders didn't support giving slaves the right to have any form of liberty much less citizenship based on soil.
I think an argument could be made that the 14th Amendment rendered the Natural Born Citizen clause void simply because the Natural Born Citizen clause was intended (in whole or in part) to ensure that the children of Indians and Slaves were not considered eligible for the office of Presidency. Therefore any provision of the Constitution that would have prevented a Slave or the Children of Slaves from being considered eligible for president would be void under the 14th Amendment. All other references to slavery or limitations on the rights of slaves were rendered void under that amendment.
As I said, the NBC clause never served it's intended purpose (to ensure undivided loyalty) and at this point is nothing more than a relic (some dead bone worshipped by people who have given up the ability to think).
I don’t see any natural or logical connection between the NBC clause and preventing minorities from being elected president.
Native Americans are really a non-issue, because at the time they were at war with them, and they truly did consider them a separate nation.
Slaves were an issue, but only because they existed at the time, not because of where they were born.
I am not among those who think that Congress does not have the power to define issues in the area of naturalization. It’s a constitutional authority.
However, it is of interest to me that Washington would not have accepted Cruz as an NBC. I think your post agrees with that if I read between the penumbras and lines.
THAT point, though, makes Cruz vulnerable, and time will show us, especially in a conservative primary, how many votes it peels off. We need to know that.
My hypothetical a while ago gives some idea of what a campaign ad could look like. I think it would be a bombshell.
