American political conservatism is distinct from its counterparts in Europe and elsewhere in the world. American conservatives have long staked their claims on devotion to limited government and free-markets, but also on an image of responsibility. Conservatives posed as the “adult in the room,” admonishing the young, the anti-war types, social progressives, ultra-liberals, environmentalists, and socialists for their radicalism and immaturity. Conservatives defended tradition, rules, hierarchy, and social conventions. Today the roles are switching. Conservatives have morphed into a new political space, while many of their more progressive opponents call for rule of law and American institutions of democracy. Conservatives find themselves the problem rather than the solution, displaying a shortsighted and toxic immaturity destructive of democratic institutions. This article explores the transformation with a focus on developments occurring in the 21st century—in America and around the world.
