“I wonder why he didn’t write the whole clause?”
Because it would have negated the whole 10,000 page diatribe.
True, but then I wonder why those who wrote this didn’t just use plain, ordinary language such as - no person born in the U.S. of a foreigner or alien is to be granted citizenship. Instead, they had to add fancy words like subject to the jurisdiction thereof. See how this would have been a much better approach? Legalese can be so elitist.
