Something tells me if something similar was done to Rush, Rush would have laughed it off. Instead, Levin decided to go nuclear, and basically alienate a good portion of his listeners who have had enough of his crusade to damage Trump (and in the process insult many of Trump’s supporters) Very amateurish.
He may be alienating some listeners, but he’s consistent with his conservative principles. As far as his career, you probably know that he’s signed both long-term radio & TV contracts.
One more thing...You give an example of Rush. Rush hasn’t endorsed anyone & yet he’s still trashed in the daily thread here by Trump supporters...
