What Rush has to worry about is his voice. When you go deaf, your brain loses its ability to monitor your voice and make sure you move your mouth the right way to make the right sounds. Eventually, you end up talking just like someone who was born deaf, which is to say in that mouth-full-of-marbles way that no radio listener would put up with for a second if they could even understand you, which most could not. Look how much his voice had changed already, and he's not even totally deaf yet.
Hopefully, the cochlear implant will take care of that, if he isn't lucky enough to get his normal hearing back. But if it doesn't, then this is sadly the beginning of the end of his radio show.
The man's served his time. Whatever he does at this point, he will always be a legend among conservatives.
All the best, Rush!
Gonna tick off the PC socialists when not only is the most popular radio talk-show host a conservative, but profoundly disabled (for the job) and coping nicely anyway.
One could even envision a voice synthesizer that converts Rush's new intonation with waveforms from the archives.
The great message that comes from this is that Rush is a man of IDEAS, and his listeners will remain loyal not for his ears or his voice, but for his views.
