The only way towners have a chance is by making sure at least one person is eliminated every round, because the Mafia certainly will. I pushed for Isaac (if only to get the ball rolling) but SOMEONE needs to go, and right now you have the most votes.
When I get back I'll move my vote if someone else is on the verge of being eliminated, but allowing votes to be stalled to no lynch only ever plays into the Mafia's hands. Someone has to go. And there is more reason to suspect you than there is usually reason to suspect ANYONE in the first round.
