I believe if he got even-handed media coverage i.e., positive when he does things right, negative when he is off, rather than the 95% negative no matter what his approval would be 55-60%. But so many people take the media at face value and it’s withering constant criticism that no one can stand up to. Although Trump is certainly better at fending it off than anyone else.
Fewer and fewer people are now taking “the boy who cried wolf” MSM at face value.
