A Failure of Succession Planning
As Rodney Hide observes, the Greens are bound by their constitution to elect either Keith Locke or Nandor as co-leader to replace the late Rod Donald.
Unfortunate for a party that was quietly trying to lessen the influence of the radicals and appeal more to the mainstream (though to be fair, none of the women in the caucus are what you would call mild centrists either).
But the Greens have decided they must pick a man even if a female would be a better choice. The result of their "enlightened", "progressive", "egalitarian" constitution is sexism. If this leads to their downfall it will be the ultimate irony, and if not, a hard lesson on the perils and injustice of affirmative action-style policy.
