Their arguments even include what I'd to this point regarded as purely my own position regarding any claim of English common law being the basis for United States conceptualizations of citizenship, having been completely negated by the right of expatriation.
I'm going to have to dig back into things, to locate just what it was that the Heritage Foundation and Edwin Meese weighed in upon, that left me with not just a strong impression but the reasonable certainty that their position on "birthright citizenship" under the 14th Amendment actually comported with that of Gray and WKA. Off the top of my head, I'm recalling that it was in dictionary form, but am not certain.
Have you ever considered posting this brief in it's entirety to FR? Somebody should. What was the ultimate disposition of the case, by the way?
