The Bush Administration, Sex, and the Moral Agenda (Manchester University Press, March 2007, pb. ISBN 0-7190-7277-8, UK£14.99) considers the White House's policy towards issues such as abortion, sex education, obscenity, and same-sex marriage. It suggests that although accounts have often emphasised the ties between George W. Bush and the Christian right, the administration's strategy was, at least until early 2005, directed towards the courting of middle ground opinion. The Bush Administration, Sex, and the Moral Agenda offers a detailed and comprehensive survey of policy-making, assesses the political significance of moral concerns, evaluates the role of the Christian right, and throws new light on George W. Bush's years in office and the character of his thinking. Order now.
