The Wire's arch drug lord Avon Barksdale was philosophical in the face of a long jail sentence: "You only serve two days, the day you go in, and the day you get out". You'd think this mentality could work best for parties consigned to the opposition benches. But no. These days, its governments that feel most hemmed in, constrained at every turn by the crushing weight of febrile politics, internal divisions, anaemic growth, and inevitable disappointment.For Malcolm Turnbull, and indeed most governments recently, Barksdale's advice seems most apposite. Although in Turnbull's case, even the day he won was pretty terrible, marred as it was by something of a hissy-fit.
