The Founders and Framers who were in Congress in 1790 passed a bill and President Washington signed it into law which said: “the children of citizens of the United States that may be born beyond Sea, or out of the limits of the United States, shall be considered as natural born Citizens: provided, That the right of citizenship shall not descend to persons whose fathers have never been resident in the United States”.
The only piece of legislation to use the term “natural born citizen.”
The Founders and Framers established the Constitution, not the Declaration of Independence as The Supreme Law of The Land [Article VI, Clause 2].
James Madison’s notes from the Constitutional Convention recorded that: One question on the qualifications of the president was among the last decided. On the twenty-second of August, the Committee of Detail, fixing the requisite age of the president at thirty-five, on their own motion, and for the first time required only that the president should be a citizen of the United States, and should have been an inhabitant of them for twenty-one years. On the fourth of September, the Committee of States, who were charged with all unfinished business, limited the years of residence to fourteen. It was then objected that no number of years could properly prepare a foreigner for that place; but, as men of other lands had spilled their blood in the cause of the United States, and had assisted at every stage of the formation of their institutions, on the seventh of September, it was unanimously settled that foreign-born residents of fourteen years who shall be citizens at the time of the formation of the Constitution are eligible to the Office of the President. (Corroboration for the statements of Bancroft are to be found in Vol. 5 of Johathan Elliott’s “Madison Papers,” page 462, 507, 512 and 521, and in Vol. 3 of Henry D. Gilpin’s “Madison Papers” pages 1398 , 1437 and 1516) — From George Bancroft’s History of the Formation of the Constitution of the United States of America, (1882 )
“...shall be considered as natural born Citizens: provided, That the right of citizenship shall not descend to persons whose fathers have never been resident in the United States”.
So the 1790 law rules out citizenship by birth for Obama, since it is well-established that his purported father was a visitor, but never a resident, of the United States.
And so it is, but the deliberate omission of the term from the next piece of legislation and all subsequent ever since, demonstrates they thought that inclusion was a mistake.
If they thought the term was infinitely malleable we would not now be having this conversation.
