Johnny, I've looked at the Constitution and the laws, as well as most of the Framers' writings on this matter

Then you undoubtedly came across this gem spoken by Mr. Madison but chose to ignore it: "It is an established maxim that birth is a criterion of allegiance. Birth however derives its force sometimes from place and sometimes from parentage, but in general place is the most certain criterion; it is what applies in the United States;"

This was spoken by James Madison on 22 May 1789. Source here: http://press-pubs.uchicago.edu/founders/documents/a1_2_2s6.html

Thanks for making my point. Speaking for the Framers, Madison clearly stated that citizenship derives from the blood and the soil.
