This book examines George W. Bush's legacy in terms of his presidential leadership and politics and explains why he was the most controversial president of recent times. It focuses on Bush's expansion of presidential power in pursuit of the "war on terror," the ideological and pragmatic foundations of his presidential politics, and the complexity of his legacy in both foreign and domestic policy. In addition to an introductory overview, it contains ten original essays that assess the problems of rating the Bush presidency, the nature of Bush's presidential government, ideology and ideas in the Bush presidency, the administration's economic and foreign policies, and the electoral context of the times.
