Update: Sunday’s recheck did indeed discover an error at the Aberfoyle Park booth which means the booth was won by Labor with 54%, not the Liberal Party with 54%. This puts the Labor two-party-preferred vote over 52%, and pretty much locks down the result.
Original post: Yesterday’s by-election in the southern Adelaide state seat of Fisher produced an unclear result, but one major party should be very happy with the result, while the other should be disappointed.
Fisher is a traditional Liberal seat – the seat was held by the Liberal Party from 1989 until Bob Such left the party in 2000. At the March 2014 general election, the Liberal Party won 57.2% of the two-party-preferred (Liberal vs Labor) vote in Fisher, which suggests that the party would have won the seat without Such’s candidacy.
In comparison, Labor won 50.9% of the two-party-preferred vote in the nine polling places used on election day. Labor won four out of nine polling places. In March, the Liberal Party won all ten polling places, with a vote ranging from 52.3% to 68%.
Independent candidate Dan Woodyatt ran explicitly as a successor to Bob Such, but polled much less than Such. Woodyatt is now polling 22.5% of the primary vote, compared to 38.4% for Bob Such in March.
While around 16% of Bob Such’s voters moved away from Woodyatt, the Liberal Party completely failed to gain those votes. The Liberal vote is currently down 0.05% compared to March, while Labor’s primary vote is up by over 10%.
I don’t have exact figures, but it appears that the number of declaration votes (which includes postal and prepoll votes) has increased compared to March. Antony Green estimates that the Liberal Party will need to do 3% better than they did on election day, which is greater than the gap in March.
If Labor holds on to their lead and wins the seat, the Labor government will regain a majority in the House of Assembly, with 24 seats as well as the support of two independents, compared to 21 seats for the Liberal Party.
For my analysis, I have split up booths into the same three areas used in the by-election guide: East, Central and West.
The ALP won 54.7% of the two-party-preferred vote in the east, and 49% of the 2PP vote in the Central area. The Liberal Party won a large 63.5% majority in the west, but the population is much smaller in that area.
|Voter group||LIB prim %||ALP prim %||IND prim %||ALP 2PP %||Formal||% of votes|
One other thing worth noting: Antony Green has identified a possible error in counting that may have underestimated the Labor two-party-preferred vote.
In seven out of nine polling places, the proportion of minor party and independent preferences flowing to the Liberal Party was clustered from 30% to 35%, but the Liberal Party received 45% of preferences in Clarendon, and over 50% of preferences in Aberfoyle Park.
If you look at the following map showing the swings after preferences, you’ll also see that the swing to Labor is much lower at those two booths. Every other booth has a swing to Labor of 7-11%, but those two booths have a swing of 2-3%. This discrepancy does not exist on Labor’s primary vote – Labor gained a swing of 9.6% on primary votes in Aberfoyle Park, although the Labor primary vote swing in Clarendon was substantially lower at 4.2%.
There’ll be a recheck of votes tomorrow, so if there is a problem it should be discovered, and this would make the challenge even more serious for the Liberal candidate.
