Our Founding Fathers said "natural born", as being born in US territories, since our Founding Fathers were not born US citizens.
First of all Bernie, there is NOTHING in the constitution about territories.
Second of all, only a few Founding Fathers (post revolution / pre constitution) were not natural citizens of the "State" which they resided.
Thirdly, the constitution is based on the French work of international law by Vattel (many of the Founding Fathers had the French original edition).
No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President; neither shall any Person be eligible to that Office who shall not have attained to the Age of thirty five Years, and been fourteen Years a Resident within the United States.
Lastly, Vattel's book is not absolute law. There are only two types of citizens, natural born and naturalized. The law defining this has been changed over time. You don't need to change the constitution to change the definition of natural born since the definition is not in the constitution. Obama doesn't qualify under Vatel either since the law was based on the parentage of the FATHER for natural citizenship. Was Cruz naturalized? If not he is either a natural born or he is an illegal immigrant.
