The election eve Newspoll for South Australia is a little more moderate than the mid-week YouGov result for The Advertiser, but nonetheless suggests Labor is in a surely election-winning position with a 54-46 lead on two-party preferred. This is from a GhostWhoVotes tweet, so more detail to follow. For further late-campaign news and analysis, see my previous post.
UPDATE: The front page of The Australian further reveals that Peter Malinauskas holds a 44-41 lead over Steven Marshall as preferred premier, and their respective approval ratings are 54% and 47%.
UPDATE 2: Full results now up at The Australian. The primary votes are Labor 41% (up two since the Newspoll three weeks ago), Liberal 38% (up one) and Greens 9% (down one) – the two-party result compares with 53-47 last time. Steven Marshall is down one on both approval and disapproval, to 47% and 46%, while Malinauskas is up three to 54% and down one to 30%. However, Malinauskas’s lead as preferred premier of 44-41 is narrower than his 46-39 lead last time. The poll was conducted Friday to Thursday from a sample of 1012.
• John Ferguson of The Australian reports Labor hopes to see a continuation of the dynamic that has been evident particularly in Melbourne, where well-heeled and well-educated electorates that have traditionally been safe for the Liberals move to the left, potentially to the extent of reeling in Davenport (8.2%), rated a possible gain by “multiple Labor sources”. Conversely, Paula Leuthen in King (0.8%) is “widely being seen as a potential saviour for the Marshall government due to her effective on-the-ground campaigning in Adelaide’s sprawling north-east”.
• Paul Starick of The Advertiser says the Liberals have all but written off Adelaide (0.8%) based on their tracking polling; that Paula Leuthen in King will be “hard to dislodge”; that #8220;both sides are confident about their prospects in Elder” (2.0%); that Davenport is “considered a prospective Labor gain by some on both sides”; and that Dunstan (8.1%) and Gibson (9.9%) are “dark horses”. However, concern among Liberals that independent Geoff Brock might dislodge Deputy Premier Dan van Holst Pellekaan in Stuart has “abated”.
• With due regard to the fact that their error margins overlap, some methodological distinctions worth noting about the 56-44 YouGov poll and the 54-46 Newspoll, notwithstanding that they were conducted by the same agency. The YouGov poll was conducted earlier, from the Monday before last through to Sunday, whereas the Newspoll was in the field from last Friday through to Thursday. The Newspoll has a sample of 1012 compared with 835 for the YouGov, but both emerged with identical effective error margins of 3.5%. This accounts for the extent to which the data was weighted to match a population profile, which was more elaborate in the case of the Newspoll (accounting for age, gender, location, education and income) than the YouGov (age, gender, location and religious affiliation). It should be noted that I can tell you all this because YouGov fulfils the transparency standards of the Australian Polling Council, which has been established since the last election. Non-members include Resolve Strategic and Roy Morgan. The methodological statements for the polls can be viewed here for the YouGov and here for the Newspoll.
