If the SCOTUS kicks the suit back to the NJ SOS, all hell breaks loose because every other SOS (49 of them, and let’s not forget the territories) will be required to validate the candidates (as they should have done in the first place.) I think the SCOTUS will seek a ruling, to prevent this nightmare (of Biblical proportions) from reaching critical mass. Either way, I say bring it on and settle this Constitutional issue once and for all. I believe that in the end, future candidates will be vetted as to their eligibility where required.
No, they won't be vetted unless they are deemed "right-wingers".
