I am hoping that after nightfall and the new headlines we will be able to get a better feel as to who the mafia is hiding in the train on Rich. I agree with Ogre that with this train you get no clues based on the voting patterns, but I am 99.9% certain that Rich non comm mafia so I do like the train in that respect and I see no other way to vote tonite.
Only 2 of the 5 remaining mafia can talk to each other at this point, so they're splintered anyway. If they can't coordinate what they're doing.. they wouldn't be able to switch votes around by planning to have one go one way while the other goes another. So even without a train on Rich.. we wouldn't learn much from their voting.
