With a more serious hat on, the greens are suffering from a severe lack of older more sensible people.
Many People like those individual in the greens and so they routinely out vote anyone who is more sensible.
I'm in the greens but unable to contribute in an active way due to family commitments. I know of GC people working at all levels and they have to remain v secret.
So anyone who fancies joining would be very welcome simply to try to swing votes. There's been increasing kickback from some brave GC greens who are out. Following certain people on twitter helps to know who to vote for in various votes.
