Respectfully, why do you suppose the framers included that phrase about jurisdiction? Using your logic they were wasted words because every baby born on our soil would be under our jurisdiction. If it doesn't mean anything why did they bother to specify TWO conditions for birthright citizenship.
I am not trying to take away the babies birthright. You are trying to give the baby rights that the framers did not intend. Post 86 gives some pretty good clues as to what the framers might have meant.
"Respectfully, why do you suppose the framers included that phrase about jurisdiction?"
Because the Indian tribes were still in possession of half of the land of the United States, and were born within the United States, but they were still their own nations, and not subject to the jurisdiction of the United States. And nobody wanted to make the Sioux and the Apache citizens by the amendment.
That's why.
Same bit about "indians not taxed" being excluded from the Census in the Constitution of 1787.
