On Rush Limbaugh's role in the decline of American conservatism, as recounted by Andrew Ferguson for The Weekly Standard, here:
The idea that conservatives should have a special interest in high culture—the best that has been thought and said, sung and played, carved and drawn—has been selectively applied. In speeches and in the [Mars Hill Audio] Journal [Ken] Myers has often raised the question of why political conservatives, who defended the literary canon, the Great Books, with such energy in the eighties and nineties, went limp when it came to defending other traditional forms of cultural expression.
A watershed may have been reached when Rush Limbaugh, who would replace William Buckley as conservatism’s chief publicist in the early ’90s, chose as his show’s theme music a Top 40 track by the Pretenders—a self-conscious contrast, Limbaugh has said, to the baroque trumpet concerto that opened Buckley’s TV show Firing Line. Buckley’s fanfare had signaled that he aspired to something lively but elevated, slightly at an angle to the surrounding popular culture. The Pretenders’ guitar riff was meant to signal that Limbaugh’s conservatism would have none of that stuffy stuff: He was fully at home with what had become of American culture and wasn’t terribly curious about what had come before.
Which is why Rush Limbaugh isn't much interested, either, for example, in the original principle of direct taxation in the constitution. American history doesn't exist for Rush before 1913, which is why Donald Trump, who believes in tariffs on China, doesn't qualify as a conservative. Rush only learned the bad stuff from Buckley . . . like how to excommunicate people from the movement. "Stripped-down" isn't just for punkers.
