Media believes there own lies.
They made their own little BS, ‘wannabe’ political universe... then acted and reported AS If, in fact, it WAS that way.
Not smart.
I don't think they do. I believe they KNOW they are misleading and advocating. They view interaction with the public as an adversarial process, wehre the press advocates the positions it prefers, and hoopes the judge (the public) will adopt the press advocacy.
Trump is correct, the press is the most dishonest recognizable group of people in the world.
