It used to be the case that participation in political life was considered to be a vocation, and that those who chose it were in it for the long haul, through thick and thin. The most prominent example of this in Australian history was Billy Hughes. Even after he lost the prime ministership in early 1923 he continued to be a member of the House of Representatives until his death in 1952.
That has all changed. Mike Baird’s resignation, both as New South Wales premier and from the state parliament, comes as somewhat of a shock. He is only 48, has been an MP for less than ten years and premier for less than three. One would have thought his best years in public life were ahead of him.
