There are hundreds of words in the Constitution that are not "defined in the Constitution" because their meaning is a given.
Read the following link...
The term natural born citizen was first codified in the legal reference book "Law of Nations" in 1758, of which was used by John Jay who later became the first Chief Justice of the U.S. Supreme Court. John Jay considered the outstanding legal scholar of his time had the "natural born citizen" clause inserted into the U.S. Constitution via a letter he wrote to George Washington, the leader of the Constitutional Convention..."The Founders required the President to be a "Natural Born Citizen" to help ensure that the ONE person sitting at the top of the Executive branch had unquestionable and unwavering loyalty to the United States of America, first and foremost.
Any Supreme Court uncompromised by expediency and dirty politics would have to decide in favor of the two-parent definition of natural-born citizen.
Therein lies the dilemma. Today, a great number (a majority?) no longer believe loyalty to the US is appropriate. The Communists(?) and other nations have so infiltrated the land, those of us who revere the Constitution are outnumbered. It seems we have under 15 years until the collapse occurs, unless God sees fit to pull this sorry mess out of the dumpster.
I, on the other hand, believe that they are craven political creatures, and that they will rule that “native” and “natural” are intended to be synonymous, addressing the same issue.
I believe:
1. Humans are totally depraved.
2. Power corrupts
