I still think it's anti-town. If you're around during the last hour or so and you vote for someone who has no chance of hanging, you're giving scum more power. No problem with trying to push someone else, even with little time left (today showed that things can change fast), but if that goes nowhere there's little point in not going for the lesser evil out of the options available.
I'm not sure what you mean about mob mentality and voting for the group.
