In lieu of anything from Newspoll or Nielsen, this week’s very interesting Essential Research survey gets its own thread. It finds Labor at what might be an all-time low for this agency, which opened for business after the 2007 election and has traditionally provided Labor with friendly results. Labor nonetheless retains a commanding 54-46 lead, down from 55-45 last week. Kevin Rudd also has his weakest personal ratings to date, his approval down three to 52 per cent and disapproval up four to 37 per cent. Tony Abbott by contrast is up a hearty eight points to 45 per cent on approval, but down only one on disapproval to 36 per cent. The likely headline-grabber of the survey is a question on the performance of Peter Garrett who gets a resounding thumbs-down with 28 per cent approval and 56 per cent disapproval. Better news for Labor on an insightful question as to whether respondents expect a Tony Abbott government would reintroduce parts of WorkChoices: 57 per cent say likely and 23 per cent say unlikely, with large majorities across supporters of all parties.
