Talk radio host Rush Limbaugh died last week.
Whatever you think of Limbaugh, he was the face of modern right-wing radio and his success coincided with a conservative takeover of an important but largely invisible force in American politics.
Glance at a list of the top 15 talk radio programs in the country and you’ll notice something immediately: All but a couple are conservative.
If that sounds surprising to you, it shouldn’t. Conservatives have dominated the medium of radio for well over half a century, and while you might think of radio as a relic of the electric age, it remains a powerful force in American politics.
