The prolific in-house pollsters at the Adelaide Advertiser have turned in another poll from a South Australian marginal seat. This time it’s the outer southern suburbs seat of Kingston, won for the Liberals in 2004 by 114 votes and reckoned by even the most optimistic of party faithful to be gone for all money this time. The poll bears this out, showing Labor’s Amanda Rishworth leading Liberal incumbent Kym Richardson 45 per cent to 34 per cent on the primary vote and 56-44 on two-party preferred. The poll was conducted on Wednesday night from an impressive sample of 724. The Advertiser also brings us the interesting news that former state Liberal front-bencher Robert Brokenshire will run in Kingston as the Family First candidate. Brokenshire was reckoned to have been one of the less deserving Liberal casualties of the March 2006 election, losing his seat of Mawson to Labor’s Leon Bignell.
