People used to refer to Paul Keating as the best Liberal Prime Minister we ever had. When Malcolm Turnbull became Prime Minister, people said that Mr Turnbull would have been a great Labor Prime Minister. Both proved far less able to deliver the ideological harmony they promised. Like Aesop’s fable of the man, the boy, and the donkey, ‘please all, and you will please none’ rings true of these short-term Prime Ministers.
