We need to get back to a central truth: the OP isn't touting CNN's (alleged) decline because he genuinely wants it to improve as a neutral source of journalism, it's because he wants it to become a Trump propaganda rag like Fox News, Breitbart or Daily Caller.
CNN does have its problems; most notably, it can over-hype the significance of something or speculate when it should stick to known facts. It's a warning about the perils of 24-hour news channels and the pressure to fill airtime. But it's still miles better than Fox, which omits 'inconvenient' coverage and downplays its news desk in favor of false claims from commentators with massive conflicts of interest.
It remains true that Trump is overtly corrupt, lies often (far more than past presidents) and routinely demonstrates gross incompetence. Any vaguely objective news outlet acknowledges those facts; the goal of the media is not to normalize fundamentally abnormal behavior.
