In making my predictions for 2015, I was tempted to predict that Abbott would last out the year, mainly on the basis of inertia, but decided it was too risky (Commenter Fran B sensibly went the other way). I’m already glad of that: even before Sir Phil, it seemed as if he was on the skids.
Assuming Abbott goes (still not certain, but looking more likely with every hour), Julie Bishop looks like a sure thing to replace him. She has looked pretty good as Foreign Minister (if you’re willing to overlook a massive cut in foreign aid), but that’s relatively easy, largely a matter of not messing up. If she does take over, she’ll need to do more than that.
To demonstrate that there’s a real change, she’ll have to break with Abbott on some major issues. Presumably that will include dumping Hockey and the most unpopular of the 2014 budget measures, but most of those are already dead.
The really big break would be to return to some kind of bipartisanship on climate change. There’s some precedent, given the way she stood up to him over going to the Lima meeting. But it would entail a break with the (numerous) denialists and tribalists in the party room and the broader party apparatus (including the Murdoch Press and bodies like the IPA). Still, if she could carry it off, she would be a force to be reckoned with.
