As secularists would have it, religious convictions should play no role in shaping the moral vision of voters and political leaders. Of course, this is itself a religious test. Violating at least implicitly the free exercise of religion, secularists assume that their own practically if not theoretically atheistic worldview should be the established religion. France tried this in the 18th century, symbolized by the unveiling of the goddess of reason in the Cathedral of Notre Dame. However, this has never been the American way. Ironically, in the nation that constitutionally disallows any establishment of a particular religion or denomination, people are free to practice their faith not only privately but in the public square.

At the other extreme, though, is the confusion of Christ’s kingdom with the United States—whether in its more liberal incarnation or as envisioned by the GOP. The rhetoric of a reinvigorated Christian right has turned off a lot of Americans who see evangelicalism more as a voting bloc engaged in identity politics than as a witness to the liberating King who has founded his own empire in his own death and resurrection. Former G. W. Bush speechwriter and policy advisor Michael Gerson offers some insightful analysis of this phenomenon on the campaign trail in recent weeks.
