Rush is a businessman first, and a political guru second. He knows his audience and prioritizes his message to them, and only shares his opinion where it fits. His success comes from this elegant balance, but this moderation of his message is also the reason I stopped listening to him.
Rush rarely uses the label "Communist" when he refers to his political opponents. Probably a good strategy, as he has roughly 25 million more followers than Ushanka. Give or take.
So it is noteworthy when he 'goes there,' as he did this week with a caller. He includes this image in his post.
