Plan A: try to switch the names on the ballot
Plan B: If Plan A fails in the courts, then: 1) resign from the Senate, 2) Gov. appoints an "annoited" Dem to the seat, 3) election postponed, 4) special election 1 year later.
I don't think it would work out that way. If the Torch resigns the Senate within 30 days, that does not effect his standing on the ballot. If Plan A has already failed, the voters still have a choice between Torricelli and Forrester in November. There is no requirement that at least one candidate be a member of the Senate.
There is no harm done to the placeholder because he does not have the opportunity to campaign for a year. He is, after all, a placeholder. He has no standing in the issue of whether or not the November election can proceed.
Now if you really want to get twisted, imagine that the Torch quits next week, is replaced by a 'Rat loyalist, and the November election goes off as scheduled. Would the 'Rat majority in the Senate dare to refuse to seat Forrester citing some BS reading of the NJ law? Could the 'Rat's possibly have that little respect for the rule of law? Have they no shame?

Discovery alone should be interesting.
