Chapman immediately joined the front bench, assuming the shadow portfolios of Education and Children's Services. She was soon touted by some quarters, within her party and in the media, as a future Liberal leader. In other quarters, however, Chapman was seen as a continuation of the factional battles that have long plagued the SA Liberals. The Liberals were cut down to only 15 seats at the 2006 election landslide. Chapman herself suffered a substantial 6.8-point two-party swing, but still retained Bragg with a comfortable majority of 12.6 percent, leaving Bragg as the only safe Liberal seat in Adelaide and one of only four safe Liberal seats statewide. Chapman was elected as deputy Liberal leader, and hence Deputy Leader of the Opposition, in an unexpected joint ticket with factional rival Iain Evans. Strong backing was received from federal Sturt MP Christopher Pyne, a longtime factional ally of Chapman, as well as another prominent boss of the SA Liberals' moderate faction, former Premier Dean Brown. She retained the deputy's post when Martin Hamilton-Smith ousted Evans as leader in 2007. Hamilton-Smith called a leadership and deputy leadership spill for 4 July 2009. Chapman ran against Hamilton-Smith for the leadership, but received only 10 votes, against Hamilton-Smith's 11, with Evans abstaining. Conservative Isobel Redmond was elected to the deputy leadership to replace Chapman. Hamilton-Smith called another leadership spill to take place on 8 July 2009, in an attempt to gain a more decisive mandate, but two days prior to the spill, he announced he would not run. Chapman again ran for the leadership but received only 9 votes, against Redmond's 13. Steven Griffiths was elected deputy leader 8 votes to 6 for Mitch Williams. 2010s Despite having attempted to previously oust Hamilton-Smith as leader and having attempted to later defeat Redmond in a leadership ballot, Chapman voted for Hamilton-Smith in his successful bid as deputy leader on 31 March 2010 in a vote held after the third consecutive Liberal loss at the 2010 election where Chapman gained a substantial 9.1-point two-party swing. Voting for Hamilton-Smith as deputy meant not voting for Evans. Chapman drew headlines in the last week before the 2010 election for not being willing to publicly refuse challenging Redmond for the leadership and faced accusations, particularly by Hamilton-Smith, of derailing the Liberal campaign, with "Chapman Could Challenge" posters hung beneath many of the Liberal "Redmond is Ready" posters. Chapman was reappointed
