Rush Limbaugh has become a victim of his own vicious rhetoric.
Like a typical bully when confronted with his anti-social behavior, he throws up his hands and says "Sorry, just kidding, no harm no foul".
And, when his sponsors, who depend on the good will of their customers, want nothing to do with him and his boorishness -- only then does he apologize with "feeling" (mostly feeling the loss of income he is about to suffer).
His insults were not an off-the-cuff misjudgment on his part. They were the product of a career full of self-serving vituperation. He neither deserves our attention nor the megaphone he has used so skillfully to sow polarization and discontent.
His retirement from the public stage can only help to bring us one step closer to civility in public discourse. We complain about a do-nothing Congress without recognizing that it is the polarizing loudmouths we applaud who set a tone that makes the art of compromise necessary for governance all but impossible.
Good Republicans are leaving the Congress after this term because no one has been able to get anything done for years in the climate nurtured by Limbaugh and those like him.
Good riddance ... don't let the door hit you on the way out.
