The new party rules are saving Shearer
This clipping is from The Listener.
Jane Clifton makes the valuable point that Cunliffe could win the party-wide vote but can’t get a majority in caucus to trigger it. Either of Robertson or Little could probably gain a majority in caucus to trigger a leadership ballot – but probably can’t win the party-wide vote. Hence you have the irony of the new rules put in place by the activists specifically to challenge Shearer, are in fact keeping him in the job.
