It is worth noting that the Greens are Labour’s closest allies in Parliament in policy terms. They have helped keep Labour in office for almost nine years now, and were dumped from consideration for Ministerial roles this time in favour of Peters and Dunne. And amazingly Keith Locke refers to Michael Cullen as having been a family friend.
Without wanting to trivialise domestic violence, it seems to me the Greens sometimes exhibit the symptoms of battered wife syndrome. They just keep staying faithful, no matter how bad the behaviour.
