Turnbull vowed to look “very seriously and thoughtfully and humbly” at the results. Bill Shorten explicitly said “we hear you” to those who voted for third parties, and has spent the days since the vote repeating a version of this mea culpa: “We understand that you are over politicians just fighting each other.” Both are right to be concerned. But the need to win over voters who are turned off by major-party politics is a greater problem for Turnbull, for a simple reason: he is in government. Incumbency was once a great advantage. But the mood of the electorate, encouraged by a faster, louder media cycle, is for protest. The raison d’etre of an opposition is to protest: the times suit opposition leaders.
