Your correct.....under NJ State Law...if the Torch resigns from the Senate with less than 30 days before the election the "new Senator" doesnt have to stand for election for 2 years.....
Not correct. Even under the reading of the law that would allow them to cancel this November's Sentate election, it would be next November (that being the second general election from the point of resignation).
But there is no way the SCOTUS would allow them to pull a scheme to extend a 6 year term into a 7 year term, especially by a law that would allow them to do that again and again and again as long as they controlled the governorship.
