The horse that I would back in Labour's leadership race isn't running. Stuart Nash hasn't put his hand up, presumably because he has figured he wouldn't win. That Nash hasn't a chance shows what's wrong with Labour.
Nash is a winner. And Labour needs a winner, more than anything.
At the last election Nash won Napier from National. He bucked Labour's losing run to score 3500 votes more than Labour's sitting MP, Russell Fairbrother, did in 2008. Nash knows how to take votes from National.
Grant Robertson is also a winner. He has held Wellington Central. But he hasn't won votes from National. He took over a safe seat.
David Parker achieved an upset in 2002, winning Otago. That was a tremendous achievement. He lost the seat in '05 and has been a list MP since. He has lost votes to National.
