Opposition Leader Steven Marshall has one of the most important, and difficult, jobs in South Australia. His first task is to ensure the Government is held accountable. His second is to make the Liberals ready to take over and do better. His third is to keep his own job – which, basically, means doing the first two well. In 2014, the Liberals outpolled Labor, but Jay Weatherill won in the seats that counted, and then outmanoeuvred Marshall in the aftermath. Today he is older and wiser. But the lessons learned need to be about the next campaign, not the last one. Around the world, these are testing political times. Voters are unpredictable, rejecting conventional leaders to vent their discontent. Today Penelope Debelle explores how Marshall aims to keep his feet and win in this uncertain and shifting landscape.
