Some advice for Labour; if you want another caretaker/stunt puppet leader to lose the next election, choose Cunliffe or Parker tomorrow. If you want a proper challenger, korero now, change in February.
In spite of Michael Appleby all but crowning Grant Robertson a Labour leader in waiting at the Aro Valley Candidates gig, it's way too soon for him to seek the top of that greasy pole. I haven't met David Shearer, but he can't have less popular appeal than Cunliffe or Parker. The latter two failed their 7 Days test and need to re-sit and do better.
Fortune favours Shearer on many fronts, not least his UN internment. Logistical know-how goes a long way in politics.
