At the heart of The Audacity of Hope is Senator Obama?s vision of how his country can move beyond its divisions to tackle concrete problems. He examines the growing economic insecurity of American families and the racial and religious tensions within the body politic, and considers the nature of threats from outside America?s borders. By returning to the principles that gave birth to the US Constitution, he says, Americans have a chance to repair a political process that is broken, and restore to working order a government that has fallen dangerously out of touch with millions of ordinary Americans.
