With few marginal seats, South Australia will be off long campaign radar 5 of Labor's most marginal seats are in Sydney's western suburbs and the fight for votes will be brutal WITH few marginal seats, expect only fleeting visits from Julia Gillard and Tony Abbott to SA in this longest, most drawn-out of federal election campaigns. As voters suffer through a summer, autumn, winter and spring election campaign, South Australia largely will be off the radar. We have maybe two to four seats in play, compared to a government-changing conga line of marginals in Queensland, NSW and Victoria where any kind of swing will determine who governs. Victorian-based Ms Gillard will visit to wax lyrical about the joys of growing up in SA and Mr Abbott will pop in for a cup of tea in a nursing home or other such photo opportunity to condemn the rising cost of living and broken carbon tax promises, but their strategy will be east from this Eden. Of SA's 11 federal seats, Liberal-held Boothby is the most vulnerable in the nation, on a margin of just 0.6 per cent. Incumbent Andrew Southcott is worthy but after 16 years in Parliament has not made the frontbench, while Labor challenger Annabel Digance is on her second attempt.

Sturt also is there to be won but Liberal MP Christopher Pyne is a wily and ruthless campaigner with plenty of experience, making it hard for Labor candidate Rick Sarre to pick it up at his second attempt. The Liberals are eyeing the swing seats of Hindmarsh and Makin but are likely to need a general swing to sweep them into their fold. Labor, backed by the State Government, will focus on how co-operation between State and Federal Labor has helped deliver nation-building decisions such as funding for roads, rail, the Adelaide Oval upgrade and SA Medical Health and Medical Research Institute as well as the River Murray deal. The Liberals are sure to talk ad nauseam about the cost of living, debt, and broken promises a la the carbon tax.
