Prediction: Dutton challenges again and wins, with Tony Abbott as his deputy.
He then leads the coalition to extinction (but not before being rolled in a midnight coup two days before election by Abbott), rather than the mere annihilation it was facing under the unaccountably liked Malcolm Turnbull. He is then invited to the Hague to stand trial for crimes against humanity (ok, that's not gonna happen).
Yeah, I dunno what's going to happen. Or care that much, to be honest. I mean I care about the medium term future after what I hope is a serious clearing of the house at an upcoming election, but care very little about the day-to-day writhings of this terminal patient.
Short of major global events that we would do best not to wish upon ourselves, nothing has changed very much in the last eighteen months. It's over. It's over the way it was over for Keating from about 1995 on, or Billy McMahon in 1971/72. Just get on it with and call an election already.
That super-ministry is a worry though. Personalities aside, if it isn't disbanded swiftly, it will solidify into permanence, like its US namesake. Can't say I'm terribly optimistic.
