Rush Limbaugh, the talk radio host who became the voice of American conservatism, has died.

His death Wednesday at the age of 70 came a year after announcing he had Stage Four lung cancer.

With his three-hour weekday radio show broadcast on nearly 600 stations across the U.S., and a massive audience of millions hanging on his every word, Limbaugh’s rants shaped the national political conversation, swaying the opinions of average Republicans and the direction of the party.

WGAN Morning News host Matt Gagnon offered his thoughts on Limbaugh’s legacy, saying Wednesday he “set the tone” for conservative talk radio, and beyond his political analysis, he offered a “sense of humor, color and fun” that cannot be replaced.

Donald Trump awarded him the Presidential Medal of Freedom, the nation’s highest civilian honor.
