Rush should retire. I used to listen to him all the time 15- 20 years ago (how long has it been)? He's done a lot for conservatism, he can explain things in a way that resonates with both wonks and barflys. I'm sure the job is physically demanding; he's suffered deafness and addiction for it.
What's point in selling your soul Rush? Retire and do one last Great Thing. Tell the truth about Trump, and demand he step aside for Pence. Do it while it can still make a difference, before the whole damn enchilada is handed over to the Dems.
To your point, I agree. Limbaugh is past his sell-by date.
To his addiction: He has had back and spinal issues in the past. Those can be painful - as a genetically-overweight late-middle-age man I can testify. He was treated with pain medicine that had the potential to be very, very addictive.
About the same time his hearing went. An odd variety of auto-immune deficiency, was the final verdict...but nobody knew then. Deafness is a problem with broadcasters, since they have different channels, to the engineer, to phone patches, or other circuits, in different earpieces. If you've ever had to listen to ONE earphone, you know it doesn't seem loud enough, ever - you crank up the volume, and over time that does permanent damage.
At first they tried hearing aids. So the problem got worse - and it wasn't something that a hearing aid could treat. It wasn't the eardrum but the very nerves which were being destroyed.
And next they tried a wide variety of drug cocktails. This WHILE Limbaugh had back issues. Bottom line is, a witch's brew of addiction got in there.
It can happen. Nobody rides Christ Matthews for being a dried-out drunk, do they? Or Gov. Ma Richards, who was a practicing alcoholic.
Limbaugh got through it. Good on him. Bad it went that way.
But the way he did, and the way success has led him to live...a very, very rarified life...has left him out of touch.
And his no longer being with the radio-station bowling league, and whatever other normal contacts he had, eventually affected both his humor and his outlook. In the vernacular of the day, he's lost touch.
This is WHY persons shouldn't hold power positions for long periods. Doesn't matter if it's a Congressman, a radio star, President of American Widget. You lose your unique insight and you become, not the problem-solver and change agent, but the problem yourself.
Time for Limbaugh to go. He can help best by bringing in some fresh blood...help them get started; use his structure and business connections to get them going.
