Rush’s ego trip is a ruse that pokes fun at liberal broadcasters.
It’s also a prediction of sorts of what liberal pundits will say whenever conservatives happen to trump them. The lefties will always trot out the “puppetmaster Rush and his robotic, brainwashed listeners” narrative (which is actually a Leninist projection - accuse your enemy of your own sins).
Rush used this to great effect shortly after Obama took office. Obama himself pulled out this very narrative I just mentioned, and Rush took all the heat and just laughed in the Democrats’ stupid faces, because it gave him more listeners and it distracted the Dems from doing anything productive (read: truly harmful).
Well, if you choose to interpret it as such. As for me, it's very obvious that there is not enough mustard to cover that hotdog, to borrow from someone's phraseology. I think that the man loves everything about himself.
