It would have to go to SCOTUS to be resolved. The definition of a NBC, as defined in the Constitution as part of the eligibility to be President, has never been tested in the courts, especially the Supreme Court. The circumstances surrounding Chester A. Arthur would have been a good test, but it was never challenged legally.
I agree with you that this is the elephant in the room clearly visible to everyone, but the MSM and the pundits totally ignore it. Obama has already admitted that his father was a British subject. And jus solis is not sufficient to prove natural born for eligibility for the Presidency under the Constitution.
Since none of us have “standing”, it is up to the vapid, supposedly educated, so-called conservative talking heads to scold us for even talking about this, I guess. It is a sad commentary that even the right wing glitterati can’t wrap their collective heads around the concept of NBC. I’ll go with Trump as a point of entertainment for the time being and munch the popcorn.
