While I suspect, depending upon his time zone, that Mr. Lamp will correct you, and know him to be very well informed, I'll save him the trouble. The 14th Amendment avoids any inference relating to natural born citizens - by design. Its principal author, Congressman and Judge John Bingham, addressed the house, twice, to explain the amendment, the first amendment to address naturalization after Article 1 Section 8 authorized Congress to create an Uniform Rule of Naturalization. Here are Congressman Bingham’s words from Congressional Archives:
"I find no fault with the introductory clause [S 61 Bill], which is simply declaratory of what is written in the Constitution, that every human being born within the jurisdiction of the United States of parents not owing allegiance to any foreign sovereignty is, in the language of your Constitution itself, a natural born citizen…"
Wong Kim Arc, reasoned upon the 14th Amendment, has nothing to do with natural born citizenship. Wong Kim, born in San Francisco, was made a citizen, not a natural born citizen. Justice Gray cited and quoted Minor v. Happersett. His foray into English common law was not relevant to Wong Kim's citizenship status (he visited China and was refused reentry by our State Department) pointless, except the extent to which it provided talking points in case President Chester Arthur's birth as a British Subject was ever discovered.
The term “native born citizen of the US”, one which Obama claimed as his own status on fightthesmears.com, was adopted by the authors of the 14th amendment to refer to residents born on our soil. The 14th made some residents born on our soil, excepting American Indians, whose allegiance was to their tribes, into “native-born CITIZENS of the US”, having nothing to do with natural born citizens of the US. It was an unfortunate choice of words, but hard to avoid. American Indians are “native-born”, but weren't at the time, made “native-born citizens.”
Obama was well “lawyer-ed” on the subject, having Larry Tribe, his Harvard Advisor, and Constitutional Law specialist on his campaign committee. (Larry may have had no choice, having been caught plagiarizing much of a book he published, and bailed out by Elena Kagan, then Dean of Harvard Law). It was Larry who wrote the sneaky SR 511 misdirection paper, now in the Senate Archives, claiming that McCain’ birth on land about which sovereignty questions remain, should be overlooked, because the framers would have wanted that interpretation. The Canal Zone was finally incorporated in 1937, the year after McCain was born. Larry may have written the statement in “fightthesmears”, Obama’s campaign website. Obama didn't lie. He didn't claim natural born citizenship. He told us he was born British. Hidden in plain sight was the tactic that depended not upon a low-information citizenry, but upon the careful and precise use of legal terms with which very few were familiar.
Again, once again - the status of those made American citizens under the 14th is of full citizenship. Not naturalization, which is something different. Their citizenship is tied to their place of birth with now American territory, or previously their lack of recognition as full persons. No distinction is drawn between those with parents born in America and between those with parents born outside of America. I can only conclude from this that the purpose of the 14th was not to naturalize all these people, but rather to establish their native citizenship within America.
