 Rann's Preferred Premier rating was at 50 percent compared to 25 percent for then Liberal leader Martin Hamilton-Smith.Third quarter 2008 polling saw a more pronounced drop in the primary vote, down three to 38 percent, with the Liberal vote up five to 40 percent, breaking to a two-party vote of 50–50 after preferences – the Preferred Premier figure recorded a six-point drop to 48 percent for Rann and up three to 30 percent for Hamilton-Smith.Some commentators put the poll slump down to "labour movement ructions" over the underfunded WorkCover liability (see 2008 Parnell–Bressington filibuster), consolidation of rural health services, and the continued degradation of the River Murray.
