In 2016, ABC election analyst Antony Green ruefully remarked that it ‘seems impossible to cover an election without referring to bellwether seats’.
A ‘bellwether’ seat is one that predicts the overall election result. For forty years, whichever party won the regional NSW seat of Eden-Monaro also won government as a whole.
But elections – and journalistic fads – change quickly, and 2016 would prove to be the bellwether’s last hurrah. As Green explained, a seat can end up as a bellwether by pure coincidence, not any underlying property of the seat itself. And by the time the bellwether seat is decided, the overall election has usually already been called.
The end of the bellwether seat’s time in the sun is a reminder that what matters are the dynamics in individual electorates, not political cliches or outdated rules of thumb.
‘Bellwether seats’ are so last decade. According to the media database NewsBank, the proportion of metropolitan commercial newspapers using the term ‘bellwether’ to describe political processes during federal election campaigns grew more than threefold between 2001 and 2007. The number of articles was relatively high in 2010, followed by a modest decline in 2013.
References to ‘bellwether seats’ nearly doubled again in 2016.
