Jones has, apparently perversely, gone the other way by insulting the members and pointing out that they are part of the problem. He wrote off a large portion of the membership as out-of-touch intellectuals who were putting off the genuine working class.
In doing so, Jones has focused on the destination rather than the journey. He has pointed out the real aim of the contest is not to be Leader of the Opposition, but to be Prime Minister in a Labour Government. He has also given a brutally honest depiction of Labour's current ability to do that. While the other two pussyfoot around talking about the need for unity and harmony, Jones is talking about the only thing that can secure that unity. That is not personality. It is the polls and power. He wants the party to be polling in the mid-40s by 2014. In doing so, he has pointed out the obvious: that the winner will have to be able to attract more votes than Labour's current core can deliver. So, he says, the members should be careful not to pick a leader who will only appeal to the already converted.
His approach might seem counter-productive at first glance. But Jones' candidacy is not simply the unnecessary, irrelevant distraction some have claimed. He has shown them what Labour needs to do on that election campaign and made them confront something nobody wanted to mention: that it is Labour, not the voters, which needs to change to get back into a strong position.
Jones' message is more than just his jokes, and that is why it has resonated at those hustings meetings, despite the sideshows about whether or not women like him and the history of his credit card use. He is still unlikely to win. But he will have achieved what he wanted, a rise in his own stocks.
His performance may also have ensured he has moved from being completely written-off to doing well enough to stop one of the others getting a majority on the first round of counting. That is why the other two - Cunliffe and Robertson - can't afford to treat Jones as simply the gooseberry on their date, because they need Jones to give a hint to his voters that they should give their second preference votes to them.
So the banter has been as vicious as things were allowed to get. They've each had their clangers. Jones made a few jokey references to Mr Robertson's sexuality in a couple of the first meetings. Jones later reflected and privately apologised to Robertson for it and has kept it out of further meetings. Jones has also copped a few back himself. The Whangarei meeting was held the same day Jones' insisted he could attract female voters from all over the country, in particular those who read Woman's Weekly instead of Germaine Greer. This sparked outrage from Woman's Weekly-reading feminists who didn't like Jones, and Germaine Greer readers who did like Jones. Some took it upon themselves, rather presumptuously, to declare on behalf of all women that no women liked Jones.
At the meeting in Whangarei, the candidates were asked which ministerial portfolios they would give to the other two. Grant Robertson said he would give Jones arts, culture and heritage "with a particular emphasis on the film industry" - a reference to Jones' porn. Cunliffe opted for women's affairs.
As for Cunliffe, neither of the others really needed to poke fun at Cunliffe. He was quite capable of doing it himself. He has declared he is the kumara people should want to munch on. In Whangarei, he began by talking to Jones' mother in the audience. He rattled off a rather confusing anecdote about Jones saying he was not her son, but her daughter.
It turned out the audience weren't the only ones confused. Cunliffe had wrongly identified Mrs Jones, and was instead talking to some other woman sitting nearby. That woman was more shocked to discover she was Shane Jones' mother than the audience was at discovering Jones was actually a wahine. The audience laughed, albeit at him rather than with him. Realising his mistake, Cunliffe added things were just getting more and more confusing the longer he went on. Quite.
