No, they wouldn't. As the NJ Legislature was operating under a Constitutional mandate when it wrote its election laws regarding the Senate, the fact that the Jersey Supreme Idiots set aside those laws without relying on any guidance from the Legislature means that they violated the Constitution.
This is (or at least should have been) fundamentally different than if the same had been tried in the governor's race. In that case, the Constitution is silent with regard to who makes the rules.
