David Shearer's shortcomings as a politician were harshly exposed during his short time as the leader of the Labour Party. On one count, however, he cannot be criticised. He knew when the game was up. "It is time for someone else to take up the challenge of leader," he said yesterday as he quit after less than two years in the role. Even if, as he acknowledged, he no longer had the full confidence of his caucus, he could have struggled on for a few more months. His was a selfless gesture designed to give his successor adequate time to mount a robust challenge to National at next year's general election.
Given that he won the Labour leadership after just 30 months in Parliament, Mr Shearer was, himself, always going to need time. Time to lose his diffidence, to learn to speak more forcefully and coherently, and to convince New Zealanders that Labour represented a capable alternative to National. Time to develop policies which would reinforce that notion by differentiating his party from others. Only in the last respect did he come anywhere near to success.
The latest polls confirmed that, despite a series of Government mishaps, Labour has failed to make inroads and its leader's standing remains low. Disunity within Mr Shearer's own party gathered pace with his inept handling of the "man-ban" issue. Two further gaffes this week - the dead fish debacle and the Prime Minister's revelation of a private Beehive meeting to discuss the GCSB legislation - were of the final-straw variety. Such episodes spoke of a hamfistedness and naivety that Mr Shearer was never able to surmount. His failure to improve accentuated negative perceptions, and nothing that he did or said could shift the political landscape.
But to some degree, he was simply unlucky. Any government should find its second term much tougher going than its first. But National continues to be buoyed by John Key's ongoing if slowly ebbing popularity. The country shows only the early signs of tiring of him and his Administration. Mr Shearer possesses qualities that at another time might have gained him widespread support. He was not, however, to receive the time to benefit from the inevitable turning of the tide against the Government.
