It seems to be something which has infected our political class generally, the idea that if only you get the right guy in charge ponies can appear. That isn't to say there's no value in good leadership, just that focusing on one guy as your problem-solver or obstacle to solving problems is a way of absolving everyone else of responsibility.
Too lazy to hunt it down, but awhile back I predicted that there was an X% chance September's new FU would be rebooted with Maliki being replaced. We must give the new prime minister a chance to succeed, blah blah. With any luck it'll be Iyad Allawi! Yay! I think X was a fairly low number, though now I'd certainly put the chance of it happening on the higher side.
