For very close to three years, until Scott Morrison beat Malcolm Turnbull for the Liberal leadership, Tony Abbott had been responsible for the worst government in Australia’s history. Morrison was worse, of course, uniquely so, a man with eight feet in a world full of rakes, but Abbott had his own special kind of appalling. He governed vindictively. He fought progress. He made an enemy of the future and found new and boorish ways to prosecute that sad fight.
