I don't agree, but we'll never know who is right now. Anyway good luck to him, if his heart isn't in it he did the right thing. He was a great Treasurer and too loyal by half.
Turnbull needs to bring the party together and refind its moral compass, could be 2 terms in opposition but they mustn't lurch to the right in trying to find the answers. Stay moderate and the electorate fatigues of the government...happens every time.
