"The rhetoric between evangelicals and Mormons has been almost abusive," said Richard Mouw, president of the Fuller Theological Seminary in California.
Christians are not a monolithic group. There are more than nine-hundred Christian denominations in America, ranging in the political spectrum from liberal to evangelical conservatives. This diversity places some limits on the power Christians have to influence political policy. Collations have been built around single issues such as abortion, especially in the evangelical community, however there is not a general consensus among American Christians.
In America of the 21st century religions influence has diminished from the days of fire and brimstone preachers of the 19th century, or even the Scopes "Monkey trial" of 1925.
Now the problem is the nation-state, "in circumstance of accelerating global integration, the nation-state has become too small for the big problems and too big for the small problems of life" Anthony Giddens, University of Cambridge.
Religion is probably a best mechanism to fill this dichotomy, however with more than three-thousand religious groups in America, there is too much diversity to ever form a national religion.
