Florida governor Ron DeSantis spoke to Rush Limbaugh last fall at a gala dinner for the National Review Institute. The radio host was there to receive the William F. Buckley Jr. award. "He actually gave me one of the greatest compliments I've ever had," Limbaugh told his audience the next day. "He listed five great conservatives and put me in the list." DeSantis's pantheon: William F. Buckley Jr., Ronald Reagan, Antonin Scalia, Clarence Thomas, and Limbaugh.

Good list. No media figure since Buckley has had a more lasting influence on American conservatism than Limbaugh, whose cumulative weekly audience is more than 20 million people. Since national syndication in 1988, Limbaugh has been the voice of conservatism, his three-hour program blending news, politics, and entertainment in a powerful and polarizing cocktail. His shocking announcement this week that he has advanced lung cancer, and his appearance at the State of the Union, where President Trump awarded him the Presidential Medal of Freedom, are occasions to reflect on his impact.

LIMBAUGH RECEIVES MEDAL OF FREEDOM

It's one thing to excel in your field. It's another to create the field in which you excel. Conservative talk radio was local and niche before Limbaugh. He was the first to capitalize on regulatory and technological changes that allowed for national scale. The repeal of the Fairness Doctrine in 1987 freed affiliates to air controversial political opinions without inviting government scrutiny. As music programming migrated to the FM spectrum, AM bandwidth welcomed talk. Listener participation was also critical. "It was not until 1982," writes Nicole Hemmer in Messengers of the Right, "that AT&T introduced the modern direct-dial toll-free calling system that national call-in shows use."

Limbaugh made the most of these opportunities. And he contributed stylistic innovations of his own. He treated politics not only as a competition of ideas but also as a contest between liberal elites and the American public. He also added the irreverent and sometimes scandalous humor and cultural commentary of the great DJs. He introduced catchphrases still in circulation: "dittohead," "Drive-By media," "feminazi," "talent on loan from God."

The template he created has been so successful that the list of his imitators on both the left and right is endless. Even Al Franken wanted in on the act. Dostoyevsky is attributed with the saying that the great Russian writers "all came out of Gogol's ‘Overcoat.'" Political talk show hosts came out of Limbaugh's microphone.
