Griffith by-election live
The third and fourth placed results are from early in the life of the Bracks government in Victoria, when Labor pulled off rare victories in Jeff Kennett’s seat of Burwood in 1999 and Nationals leader Pat McNamara’s seat of Benalla in 2000. Also higher up the order than Griffith is the Elizabeth by-election of 1994, held four months after Dean Brown’s Liberal government came to power in South Australia. This may have indicated the popularity of outgoing member Martyn Evans, soon to be Labor’s federal member for Bonython, who had been designated as “independent Labor” for most of his ten years as a state member. Rob Borbidge’s Queensland government of 1996 to 1998 did less well, with the looming Liberal collapse in that state foreshadowed by swings to Labor in the Brisbane seats of Lytton and Kurwongbah.
All of this is laid out in the chart above, which ranks swings to the government (positive at the top, negative at the bottom) from the eight federal and eight state by-elections just discussed. Red and blue respectively indicate Labor and Coalition governments, the lighter shades representing state and the darker representing federal. Stats enthusiasts may care to know that the model y=10+44.3x explains 38% of the variability, where y is the government’s eventual longevity in office measured in years and x is the swing to the government across 15 observed by-elections. For what very little it may be worth, the positive 0.5% swing in Griffith associates with 10.3 years in government.
