Senator Cruz is not running for POTUS right now. IF he does, I think it likely that, unlike the phony poseur currently staining the office, he would seek a Constitutional ruling regarding his qualification for the office of the POTUS which he like our Founders holds sacred (and he should have “standing”).

Who would make this final ruling and would you accept the decision like it or not ???
Of course, that will be debated too. Legislature or Courts? We can be certain that it WON'T be by amateur Constitutional 'scholars' opining on it here. IMHO, SCOTUS will make it official that the current acting interpretation in the 'modern political environment' of "natural born citizen" = "born citizen" (i.e. child of an American citizen, including a mother named Eleanor).
would you accept the decision like it or not ???
Yes, I would. What will be will be.
