The latest quarterly Newspoll survey of South Australian state voting intention has Labor’s lead at 53-47, its lowest in three years. This compares with 56.8-43.2 at Mike Rann’s landslide re-election in March 2006. Labor’s primary vote lead is 41 per cent to 37 per cent: on both measures the two parties have exchanged 1 per cent since the survey from the previous quarter. Liberal leader Martin Hamilton-Smith, who I haven’t been paying much attention to since he took over the leadership from Iain Evans early last year, has an encouraging satisfaction rating of 45 per cent against 25 per cent dissatisfied. However, Mike Rann’s satisfaction rating is up from 51 per cent to 53 per cent, and his preferred premier lead has widened from 50-25 to 54-24.
