Going by the VA legal definition of bribery, I'd say that there was a pecuniary benefit by him resigning his job, and would benefit a sitting senator and state representative by influencing the main roadblock to their party's majority to resign and allow their positions to become law of the land in the Commonwealth.
I'm interested in your point, but looking at the legalese, I'd say it's a bribe.
It seems like it's a matter of trying to ascertain a person's thoughts at a particular time, which is what I think of as the parallel with desertion. At this point it's not clear what if anything was said and by whom about the Tobacco Indemnification Commission job. Is he guilty of bribery if he is offered a position in the event that he retires, even if he was planning on retiring anyway? Maybe the letter of the law does say that, but it would follow in that case it is illegal for a person with elected office to ask or converse about or accept another paying job since any hint of an offer would be for a pecuniary benefit. In that case it is extremely strict.
