For me, it's a toss up between
@chart94,
@Spitfire6532, and
@EyehatethePEexam PE. Eye has already voted for known mafia twice, so that would be a bad move on their part. So they are least likely mafia. SF has voted only once for mafia, but they lead the charge to vote out steel. Could have been a move to throw us off that backfired on them, but we shall see. And chart has only voted for known townies the whole game. Of course, a slight assuption that JP and RBH are townies, but that seems highly likely this round.
Based on that,
@DLD PE I vote for
@chart94
