I think its a bit too late for this now, I can only suggest that you and Stein (if true) pile onto the same guy and hope he has more votes than you.
Already said this when he claimed to be a Mason earlier, if he is lying the masons will be voting for him and he will swing, if not him and the other will vote the same person and chaos would need loads of votes to actually swing. Should be easy enough to figure out.
