In June 2013, however, Rudd regained the prime ministership. Glasson was unsuccessful at the September 2013 federal election, with Rudd retaining Griffith with 53.0% of the two-party preferred vote, representing a 5.5% swing against the ALP. This swing was the largest suffered by a Labor incumbent in Queensland at the election. Glasson led Rudd on primary votes by 42.2% to 40.4%. In his concession speech after losing the prime ministership to Tony Abbott, Kevin Rudd said "it would be un-prime ministerial of me to say "Bill Glasson, eat your heart out", so I won't". Rudd resigned from Parliament in November 2013, and a Griffith by-election was held on 8 February 2014. Glasson again contested for the LNP, but was defeated by Labor's Terri Butler. In May 2015 Glasson unsuccessfully sought preselection for the casual vacancy in the representation of Queensland in the Senate caused by resignation of Senator Brett Mason. One of nine candidates, he was defeated by Joanna Lindgren on the final count. The "Sydney Morning Herald" reports that Lindgren was a "surprise candidate" who "opposes gay marriage, abortion and euthanasia" after Glasson was "called in" to explain his support for gay rights. Glasson's wife Dr Claire Jackson is a general practitioner and former president of the Royal Australian College of General Practitioners (RACGP). Bill Glasson himself is an Honorary Fellow of the College. They have three children, two daughters and a son. In the Australia Day Honours 2008 he was appointed an Officer of the Order of Australia, for services to medicine in rural and remote Australia, to the eye health of indigenous people, and to professional medical organisations.
