Kathleen Geier answers What’s different about today’s conservatives? "The main difference between the conservative movement then and now is that elites like Buckley have lost the ability to define the movement. Today, conservatism is less hierarchical, and more diffuse. It’s not that conservative elites don’t wield considerable power in the movement, of course. But within conservatism, there is no longer anyone of Buckley’s stature who has the power to define the boundaries of the respectable right, and to purge certain individuals or tendencies. The closest thing to a leader today’s conservative movement has is Rush Limbaugh, who delights in voicing extremist opinions and trafficking in the kind of inflammatory rhetoric that many voters find repellent."
