The Advertiser has two polls of Adelaide seats conducted by YouGov Galaxy, one from Labor-held Lee, the other from Liberal-held Morialta.
In Lee, Labor front-bencher Stephen Mullighan trails the Liberal candidate by 39% to 34% on the primary vote, with everything depending on preferences from SA Best, who are a distant third on 18%. Galaxy estimates that this translates into a two-party result of 50-50, but this would seem to be highly speculative.
The Morialta poll has SA Best clearing the first hurdle, outscoring Labor by 25% to 21% on the primary vote, unless preferences from the Greens on 6% closed the gap. However, Liberal incumbent John Gardner is estimated to emerge 52-48 in front, from a primary vote of 40%. The SA Best result is consistent with a statewide vote more in line with the 24.9% it recorded for the Senate in 2016 than the 30% plus figures that were coming through in earlier Galaxy polling.
A better premier question has Jay Weatherill on 31%, Steven Marshall on 25% and Nick Xenophon on 22% in Lee; in Morialta it’s all but a three-way tie, with Xenophon 28% and Weatherill and Marshall on 27% each. The polls were conducted last Wednesday and Thursday from samples of 520 in Lee and 505 in Morialta.
