In the wake of the death of conservative radio pioneer Rush Limbaugh, former Minnesota Congressman Jason Lewis, who hosted his own radio show for years, says Limbaugh’s ability to inject humor into his program, often at the expense of his political rivals, made him an effective and entertaining host.

“The one thing they cannot tolerate is people making fun of them, or irreverence, and he did that right from the get go, and that A captured people he might not have otherwise captured, but B made the point in the most profound of ways, and I think that was his real secret.”

Limbaugh hosted his program on stations coast to coast since the late 80s, and ratings over the years showed him to be one of the most listened to radio hosts in America. He died Wednesday after a battle with cancer. He was 70 years old.
