Hollywood's, and particularly, Stephen Colbert's obsession with Trump blinds them to the fact that America views them first and foremost for entertainment. And when all you know is "slam Trump/slam Republicans," after 12 years of that schtick, it gets mighty tiresome and people tune out.
Of course, this is merely belying the fact Hollywood and the likes of Colbert really have no talent, innovation, or anything new to offer the American public. Just like most of today's artists, they suck, and then use leftist political messages in their paintings, sculptures, poetry, and architecture to obscure this fact.
Yes, Stephen, I know you and everybody younger than you were brainwashed to hate conservatives, republicans, America, and white people in K-college. But even with this huge indoctrinating/marketing/religious advantage, people get sick and tired of politics and sometimes actually want politics-free entertainment. Alas, I'd like to say, "so get your monkey ass back in the cage and do a little dance," but you and most of Hollywood can't even muster up the artistic creativity to do that.
But by all means, please do make your life career "slamming Trump," and thus letting Trump define your lives. Nobody is watching anyway.
