Will Hodgman's surprise resignation has brought Tasmania's long running political dynasty to an end, and represents that rarest of things in modern Australian politics: an exit on his own terms.

This is particularly true of state premiers, who in recent years have had a tendency to burn through their early popularity, or, at best, hang around on the backbenches for a few months after leading their party to defeat.

On the numbers alone, Hodgman's achievements are remarkable. Firstly, he was the Liberal party leader for 14 years, a phrase that in itself feels old- fashioned and incongruous, like riding a penny farthing to work or cocaine in a soft drink.
