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.
