Being a ‘birther’ I have often wondered why the Founders did not be more explicit as to the meaning/description of an ‘NBC’ which they so uniquely embedded in the Constitution for POTUSA . It is well known that the Founders were much aware of the talk/discussions about ‘NBC’ and even had communications as to such. With years of dealing with laws, rules, regulations, specifications, etc. I have often been involved in presentations which assumed that somethings not mentioned were taken as ‘a matter of fact’. I believe that is why the Founders did not write ‘a matter of fact’ appended to the requirement for ‘NBC’. Much like when they signed the Constitution they did not declare themselves as citizens of the States.
Because they needed not be explicit!
At common law, with the nomenclature of which the framers of the Constitution were familiar, it was never doubted that all children born in a country of parents who were its citizens became themselves, upon their birth, citizens also. These were natives or natural-born citizens, as distinguished from aliens or foreigners.
In other words is was common knowledge
With people of the same sex now getting married, 100 years from now some idiot in a forum is going to claim that the founders didn't define parents!
