You need to understand that everything that we ever see or hear an establishment politician do is theater. Just like every advertisement is literally a message from somebody else trying to manipulate you into spending your money in this or that way, every word that ever passes over the lips of a politician is meant to manipulate you into keeping them in power and allowing them to do what they want to do. Them showing you that they are angry does not mean that it is their honest emotional state, it means that they think they can benefit by making you believe that they are actually angry. I expect that their honest emotional state is rather dispassionate and detached. They know the game and they have played it a long time. The reason they think it benefits them to make you believe that they're angry about Trump is that he wasn't part of **their** establishment and he didn't play the game by their rules. Therefore you are supposed to believe that you should treat Trump as anomaly to be upset about, and you should let them get back to playing the establishment game that they were playing for decades before Trump ever became president.
