Four leaders for a party in opposition unprecedented.
Far too late for his own good, David Cunliffe has done the right thing by resigning. He has done the wrong thing in deciding to stand for the Labour leadership again but that probably will not matter.
It seems most unlikely that party members and affiliated unions will foist him on the caucus a second time. As the general secretary of the largest, the EPMU, told the Weekend Herald, "Quite a big thing [has] happened in the meantime and it was called an election."
Mr Cunliffe's resignation has forced the party to find a new leader urgently. This time it must choose the right person. It has had three leaders since Helen Clark stepped down and none have been quite right.
Phil Goff had been around too long to present a new face, David Shearer had not been around long enough to find his feet and was too diffident, Mr Cunliffe never had the confidence of his caucus and now the country has seen him perform.
