This week’s Morgan face-to-face survey carries a shocking headline figure for Labor of 55.5-44.5 to the Coalition. However, it’s less than bad for them using the industry standard measure where preferences are allocated according to the results of the previous election, rather than as indicated by respondents, which has it at 53.5-46.5. This slightly edges the 53-47 result of March 26-27 as Labor’s worst performance since the election. The driver is a big hike in the Coalition primary vote from 43.5 per cent to 48 per cent, with Labor down a point to 36.5 per cent and the Greens down 2.5 per cent to 9.5 per cent.
On the subject of preference allocation, it should be noted that Labor’s preference share on the Morgan respondent-allocation measure has been fairly steadily declining since the election, as shown in the chart below (which smooths things out by using a three-week rolling average). The upshot of this is that the preferences distributed by how electors voted at the 2010 election figure might be flattering Labor a little.
In other news, today has seen the release of the full data from the Australian Election Study for the 2010 election, an ongoing academic endeavour which targets a sample of about 2000 respondents with questions on voting intention, issue stances, party identification, personal background and a plethora of other information. I’m currently mining this for findings of interest and will add them to this post in due course.
