That's certainly a scenario out there. I was involved in a discussion of this over dinner and the issue was raised of another possibility.
It may be a last ditch shot in the dark by the Dems. It's certainly possible that they realized Toricelli was unelectable and certain to go down in November. That would mean they have nothing to lose so they took a shot in the dark in hopes of having a slight chance at hitting something.
The big question IMHO is why Toricelli waited to withdraw. He apparently could have done so only two weeks ago without any legal controversy, yet he waited. Things changed for the worse against him since then, but I don't see how Toricelli could not have expected it. It seems like the only logical thing is that the Dems saw a situation go from bad to hopeless. Therefore they tried a drastic manuever with slim, albeit better, chances to do something.
The power of self denial, even in the face of plummeting poll numbers, is an amazing thing.
Then the 7-11 video was released, and things went from bad to horrrible. You could SEE The Torch acting like a crook, instead of just reading about it. (Visuals are ALWAYS important, and we should take a lesson from this.)
Their behavior sounds to me like a scramble thought up by the Head Weasel, Bill Clinton, and to me the best thing is to go to the court, then drop it if we lose and run against Lautenberg, because he is very beatable.
