What goes by the description of "conservatism" these days is a far cry from its past incarnations. Forget the legacy of moderate conservatism promoted by Dwight Eisenhower. Today's conservatism, according to Robert Brent Toplin, has taken a decidedly radical turn.

Toplin offers an intriguing critique of this fast-growing movement that resembles religious fundamentalism--a rigid true believer's mindset that dismisses opposing views and leaves almost no room for dialogue. Toplin observes that the right's orthodox approach represents a significant rejection of the more open-minded and practical outlook that characterized both liberal and conservative politics in earlier years.

Toplin considers three major subgroups within radical conservatism: stealth libertarians, who espouse free markets and small government, culture warriors, who crusade for morality and "values," and hawkish nationalists, who favor military solutions in foreign affairs. He points out that, whatever their differences, these groups manage to unite behind a common loathing. Conservatives demonize liberals, blaming them for most everything they dislike in American life. But, as Toplin shows, their view of "liberals" has little to do with reality, for it treats everyone from the center to the far-left as a liberal and equates liberal ideas with extremism.

When Americans talk about radical conservatism, they usually think of strident commentators on radio and television such as Rush Limbaugh, Sean Hannity, and Ann Coulter. Toplin offers a much broader picture of the radical, fundamentalist mentality. He shows that a religious-like approach to political ideas can also be found in the thinking of prominent scholars, journalists, and public officials such as Milton Friedman, William F. Buckley, Irving Kristol, Allan Bloom, George Will, Fred Barnes, William J. Bennett, and Ronald Reagan. Toplin finds political fundamentalism at work, too, in media outlets like the Fox News Network and the Wall Street Journal and at think tanks such as the Heritage Foundation, the American Enterprise Institute, and the Cato Institute.

Offering a roadmap of the radical right's emergence over the past half century, Toplin reveals how enthusiasm for a conservative "faith" helped to erect a bully pulpit in an increasingly powerful political church.
