Rush's retirement would give news/talk radio a shot in the arm. He's still seen as the face of the format -- the style by which all talk radio is judged by people who don't bother to seek out the good stuff. There are plenty of hosts out there who don't think news means nothing but politics. They don't sound angry all the time -- to the contrary they sound like they're having fun.
There's been a lot written lately about the shift in talk radio away from politics, but often it's portrayed as a choice between political talk and lifestyle talk. That ignores the huge middle ground of what "news/talk" used to be -- a host discussing the news of the day, be it politics, the economy, technology, consumer affairs, crime, severe weather, entertainment or whatever. Rush started out that way with an emphasis on politics but eventually morphed into nothing but politics.
Aside from the political monotony and maybe as significant, Rush today sounds like a cranky old man. His voice is hoarse and strident -- he sounds like the guy in the nursing home clip at the beginning of Simon & Garfunkel's "Old Friends!"
It's time for Rush to retire and help restore the image of talk radio.
