From World Magazine's review of Newt Gingrich's new documentary "Rediscovering God in America II: Our Heritage":
On balance, the film doesn't dig very deeply into the issue of religion in civic life. But the Gingriches avoid some controversy by refusing to name America a Christian nation outright. One difficulty may be that the Gingriches themselves are narrating a film about values in American society when Callista is Newt's third wife and his former mistress.
