Cornes' first political involvement began when she was approached by family friend and State Deputy Premier Kevin Foley to run as the Labor candidate for the South Australian Division of Boothby in the 2007 Federal election, reportedly after her husband declined the nomination. Cornes admitted at a press conference that she had previously voted for the Liberal party, specifically for political opponent Liberal John Howard, and had written about him as a "fine PM" in her newspaper column.
