“Three Nationality Harris is not a natural born citizen.”
So, Harris was born with the right of citizenship & the duty of allegiance to three different nations? Which would mean at some point she would have needed to declare one citizenship over the other, which in my opinion is what naturalized citizens do, they choose to surrender a birth citizenship or citizenships for U.S. citizenship.
Precisely, natural born citizens are naturally citizens because they are born here of citizen parents, could not be anything else and have ONE nationality, ONE allegiance, ONE loyalty.
