 Newspoll early in 2007 saw Rann peak at a historic 64 per cent as Preferred Premier, and 61 per cent on the two-party-preferred vote.University of Adelaide Professor of Politics Clem Macintyre said that after the State Bank collapse, Rann had to re-establish Labor's credentials as an economic manager as a matter of urgency, and "in that sense Rann had a whole lot of priorities to concentrate on that Dunstan didn't even think about", with a legacy built on economic achievements, achieving the triple-A credit rating, as well as its capacity to deliver infrastructure projects.Fourth quarter 2007 polling saw a reduction in the strong support for Rann's Labor government since the previous election, on 54 percent of the two-party-preferred vote, a fall from the previous poll of five percent.
