By all means, fight.
But recognize that states where a delusional communist got 56% of the Presidential vote in 2000 will, in all likelihood, have two RAT Senators. It's not your fault, it's not the fault of the courts. It's the fault of the morons who live in your state.
Forrester must make the case (not hard, IMO) that he would be a better Senator than Lautenberg. Force the Dems to announce they will replace Lautenberg after he's elected. Expose the whole process for the farce it is.
My point is not that you should not fight (although I don't think it's wise to fight in the courts).
My point is that, in all the Republican "New Jerseys" in America, there are fourteen RAT Senators who should be defeated easily. It is unwise to waste effort or emotional energy on NJ that should be spent ridding the Senate of RATs from the Dakotas, Georgia, etc, etc.
