Remember this 2010 classic from when the coalition talks were going on, went something like this
stuscfc: We should all vote BNP next time, not saying I agree with them but it would make the main parties sit up and try to reconnect with what the man on the street wants.
Imposter: well why don't we do that same idea but with the Green party?
stuscfc: No chance, what if they won and introduced some of their more loony ideas
