This is how you handle the subject. Get Trump elected, then have the DOJ investigate and make a presentation to the SCOTUS asking for a ruling if such a person is eligible under.
You ask the SCOTUS to define the term and eligibility for future generations.
That's rather a crap shoot, isn't it?
The liberals will all vote "anybody is a citizen" and the conservatives might vote, only children born to people with no other allegiance, are citizens, and the weather vanes in the middle will vote whichever way they think their friends think.
I don't like the idea of facts being decided by Democracy. Facts are stubborn things, and they continue to be true even when people don't believe in them.
For all intents and purposes, the issue is dead, with the most worthless interpretation being the one most widely believed.
All a Supreme court decision would do would be to lock in the wrong understanding of things, like they did for so many years with Roe v Wade or Plessey v Ferguson or Wickard vs Fillburn.
