Newspoll’s transition period from YouGov to Pyxis Polling is not yet complete, leaving us without a new set of numbers in over five weeks; we are in an off week for the fortnightly Essential Research series; the monthly Resolve Strategic was last with us a fortnight ago; and while Roy Morgan’s two-party numbers should be with us today, I don’t think we get the primary votes until later, and it’s past time for a new post already. So in the absence of new poll results, let’s reheat some old ones, in the shape of the following LOESS trends from the four regular pollsters since the last election, on two-party preferred and the Labor, Coalition and Greens primary vote. Note that the two-party preferred data is based on my own calculation using previous election preference flows, and not whatever the pollster uses for its headline.
• Resolve Strategic has been Labor’s best series throughout the term, and to the extent that it appears that may be starting to change, it’s largely down to their most recent result. The series has consistently been higher for Labor and lower for the Coalition than Newspoll, but tracked very closely for the Greens.
• Essential Research has been distinctive in its high ratings for the Greens, who have been tracking at about 14% throughout this year even before excluding the pollster’s undecided component of 5% to 6%.
• Roy Morgan’s Coalition vote took a dive late last year that didn’t register anywhere else, leading me to suspect a methodological change. It’s since been about equal with Newspoll and Essential on two-party (at least until very recently, which may prove an anomaly) and at the high end for all three on the primary vote, which is to say it’s been low for “others”. I can’t be entirely sure about that though, because the numbers in its primary votes table consistently sum to a few points north of 100% (UPDATE: It’s pointed out to me that the table is missing a column for One Nation, whose support you can estimate as the balance of the other columns, not counting the uncommitted one).
