Peter Costello has refused leadership of the opposition
. This is a very clever move on his part. Despite John Howard's nomination as successor, there would almost certainly be at least one challenge for leadership. Without Mr Howard and without government, the party may well also suffer the internal strife and division that most opposition parties on the state and federal level suffer these days. The last thing Mr Costello wants is to be the next Kim Beazley.
So what will he do? Maybe he'll sit back as Joe Hockey and Alexander Downer and whoever else tear eachother down, safe from the mudslinging and relatively untarnished in reputation. Then in a few years he'll be poised to step in and finally take the leadership role as John Howard did before becoming prime minister. Or maybe he really has had a gutfull and he's content to serve out his term before going into the private sector to get his back scratched. God knows I would in his shoes.
Either way, it should be interesting to watch.
In the same article linked above, Mr Costello attempts to blame the media for his party's low poll result. Make of that what you will.
