Historian Randall Balmer takes us on a tour of presidential religiosity in the last half of the 20th century - from Kennedy's 1960 speech that proposed an almost absolute wall between American political and religious life to the soft religiosity of Lyndon B. Johnson's Great Society; from Richard Nixon's manipulation of religion to fit his own needs to Gerald Ford's quiet stoicism; from Jimmy Carter's introduction of evangelicalism into the mainstream to Ronald Reagan's co-option of the same group; from Bill Clinton's covert way of turning religion into a non-issue to George W. Bush's overt Christian messages, Balmer reveals the role religion has played in the personal and political lives of these American presidents.

God in the White House explores the paradox of Americans' expectation that presidents should simultaneously trumpet their religious views and relationship to God while supporting the separation of church and state. Balmer tells the story of the politicization of religion in the last half of the 20th century, as well as the "religionization" of our politics. He reflects on the implications of this shift, which have reverberated in both our religious and political worlds, and offers a new lens through which to see not only these extraordinary individuals, but also our current political situation.
