I don’t think there’s any doubt that all Americans are harmed if the constitutional standard is not met and vouchsafed to us. Also, there is intrinsic “constitutional harm” in seating an ineligible President.
That said, one of the great problems here is that there is no procedure or process for vetting the nominee. At this point, it seems to be left solely to the haphazards of politics. However, even if a congresscritter or an elector got up the gumption to challenge a President-elect’s qualifications, the procedure for that is not clear, the *standard* is merely implied, and the remedy (who has standing to challenge the result or compliance and on what grounds) obviously is unclear.
It appears to be a very complicated process but worth it. There are many on FR who would rather not even try to define natural born citizenship but avoiding this fight really is disrespectful to all those who fought for this country and died specifically for the survival of America and its Constitution. To let this issue die would be such a betrayal. Sure, we all have to live together but we all have to live by the law and be judged equally by it.
