NJ is full of corrupt judges. The obvious ploy is to refuse to consider the issue unless he wins the Republican nomination. Then, if and when—which if frankly doubtful, no matter how much he cheats and lies—they can bring the hammer down on him.
However this judge’s ruling is advisory only. The decision now goes to Kim Guadagno who is New Jersey’s Lieutenant Governor & Secretary of State. The politics are fascinating since Governor Christie has endorsed Donald Trump and his Lieutenant Governor can accept, reject or accept in part this judge’s advisory opinion.
If the plaintiff isn’t satisfied with Kim Guadagno’s ruling, he can appeal to the New Jersey Superior Court which is the appeals court in that state.
