Is there more info here TW? Right now this seems beyond odd. First, what was said or alleged to have been said? Second, why is an elective office considered to be a property right or rather, why would one be able to place a claim on it?
That said, the Susan B Anthony Folks are an anti-choice feminist group with their own agenda and a history of playing rough. If it can be shown that they committed libel, then maybe. Still, it seems you would have to prove that they knowingly told a lie, and but for that lie that the election would have gone the other way, and second guessing an election is not something a sane judge will do without overwhelming evidence. That's just for starters. You would also have to show that the candidate was somehow entitled to his salary. To me, this seems like a damn tough row to hoe. I don't have any facts to go beyond laying out the legal theory, but this one just seems damn weird.
