It was easily thought that the election of a Federal Senator would fall under review for adherence to the Constitution:
Article OneThe federal perview also comes about under the Equal Protection provisions, although, not as comprehensively as it did in Florida...ergo the one sop here that allowed the wishy-washy to duck the issue.
Section. 4. The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.
No, I wouldn't have had a problem with their review, especially since the NJSC shouldn't have rewritten law reserved to their legislature in the first place.
