Pita Sharples' resignation as co-leader of the Maori Party may be too little too late as far as strengthening the party's chances of surviving as a parliamentary force goes.
Sure, it removes the major irritant of disunity at the top of the party. That is assumed to always to be a vote-killer.
The handover of the co-leader's role (almost certainly) to Te Ururoa Flavell, who had made a putative challenge for the job, definitely deals with that problem which cost the party so dearly in last Saturday's Ikaroa-Rawhiti byelection - or supposedly cost it dearly.
In fact, the Maori Party candidate basically did no better or worse than he did in the general election in 2011.
What happened was that the Mana party picked up votes that went to Labour in 2011, thereby leapfrogging the Maori Party and capturing second place from its foe.
