Keynote address by Noah Feldman at the Mormonism & American Politics conference entitled Persecution and the Art of Secrecy: An Interpretation of the Mormon Encounter with American Politics.Mitt Romney's run for the White House raises perennial questions about the place of religion in the public square and offers scholars an interesting occasion to reconsider the relationship between religion and American politics. The media has made much of Romney's religion and so have some sectors of the American public. What can we learn from public attitudes about Mormonism? Are the religious beliefs of a political candidate relevant to serving in office, and if so, how? Are there political implications to Mormonism? Do the careers of other Mormon politicians shed any light on this question? In what ways is Mormonism politically comparable to other religious groups?
