When RUSH first came on the air there was no FR, no instant news on your handheld smartphone, no streaming video or audio, the internet use was in it's infancy. It was like when there were only 3 TV channels - no competition for ideas. RUSH never modernized his program with the times, he's become flat and predictable. He forgot who he was and this whole infatuation with Cruz and disdain for Trump will be his jump the shark moment.
I discovered Rush on a transistor radio while walking down a beach in St. Augustine, Florida in 1989. His show was truly revolutionary, as up to that time all you had was the mainstream print media, Big 3 networks and CNN.
His show was much funnier back then. Humorous updates, comedy skits, etc. He’d be wise to quit pontificating and go back to that.
