Conservative voices dominate AM talk radio. Is this a good thing for conservatives? John Derbyshire makes a strong case that talk radio has contributed to the dumbing down of the American Right.

With reasons for gratitude duly noted, are there some downsides to conservative talk radio? Taking the conservative project as a whole—limited government, fiscal prudence, equality under law, personal liberty, patriotism, realism abroad—has talk radio helped or hurt? All those good things are plainly off the table for the next four years at least, a prospect that conservatives can only view with anguish. Did the Limbaughs, Hannitys, Savages, and Ingrahams lead us to this sorry state of affairs?

They surely did. At the very least, by yoking themselves to the clueless George W. Bush and his free-spending administration, they helped create the great debt bubble that has now burst so spectacularly. The big names, too, were all uncritical of the decade-long (at least) efforts to "build democracy" in no-account nations with politically primitive populations. Sean Hannity called the Iraq War a "massive success," and in January 2008 deemed the U.S. economy "phenomenal."

Much as their blind loyalty discredited the Right, perhaps the worst effect of Limbaugh et al. has been their draining away of political energy from what might have been a much more worthwhile project: the fostering of a middlebrow conservatism. There is nothing wrong with lowbrow conservatism. It's energizing and fun. What's wrong is the impression fixed in the minds of too many Americans that conservatism is always lowbrow, an impression our enemies gleefully reinforce when the opportunity arises. Thus a liberal like E.J. Dionne can write, "The cause of Edmund Burke, Leo Strauss, Robert Nisbet and William F. Buckley Jr. is now in the hands of Rush Limbaugh, Sean Hannity. … Reason has been overwhelmed by propaganda, ideas by slogans." Talk radio has contributed mightily to this development.
