Dunkley byelection, page-452

And again you have used a figure of 4% as an average. BUT.. You also failed to see that Antony then said that the average swing in a Labor seat when there is a Labor govt in Canberra is 8.2%. That is exactly what Dunkley is.............a Labor seat in a Labor government.

"At the eight by-elections in Labor seats during Labor governments, the average swing was 8.2%"

Libs achieved less than half that 8.2% average.
