That leaves Turnbull and Nelson to bitch slap it out.
Seeing as neither man is likely to want to play second trollop to the other, that leaves the deputy leadership waiting for a taker.
Have not heard a peep out of Nelson, but Turnbull is busy spruiking himself to journalists:
"Mr Turnbull said he was not like outgoing leader John Howard and not an ideologically-driven person.Your hindsight Mal, perhaps, and all the journo's, the experts, and the historians.
"We're two completely different people," he said.
"My approach would be one that is much more objective about policies.
[News flash Mal: no one is objective about policies. Does he mean pragmatic perhaps? Or easy? Or popularist? If so, he shouldn't start off on the wrong foot by trying to pass pragmatism / ease / popularism off as objectivity, it won't wash.]
"I am not an ideological person. I am a practical person. I come with a long experience in business."
[Three long years in politics and Mal still isn't getting it: being a merchant banker isn't the same skills set as running the country. Politics isn't, and has never been, the art of practicality. Besides, there are only 36 practical business people in the entire world, only 8 of whom live in Australia.]
Mr Turnbull said history would judge whether Mr Howard had stayed too long in the Liberal leadership.
"I think, with the benefit of hindsight, that will undoubtedly be the judgement of history," he said.
"John Howard is in his last days as prime minister. He's packing up his house and so forth. I don't want to sit here today and criticise John Howard. This is not the time for it.
[He'll wait until later - everyone will - then they'll rip the guts out of the "bestest ever" Prime Minister.]
"But the proposition (that he stayed too long) is one that will be universally held by historians.
"Of course, we all have 20-20 vision in hindsight."Your hindsight Mal, perhaps, and all the historians.
I first predicted the massive Work Choices blow-back, and that Howard would pull the entire party down with him by not retiring, as far back as 18 months ago. I was howled down. Every time I repeated myself since then, I was howled down. Where are all you geniuses now, hey?
I suspect Turnball will get the leadership, but he is not even close to being job-ready, as it were.
We've already had one "Mal" as the PM. I predict we will never have another.
