To be fair, the media spreads so much misinformation, it's crazy. There have been so many instances where stuff is said here that is so wrong and misrepresented, it becomes this huge mountain to deal with and not really worth the time. Look at the rise of Fox News. There is a market for alternative news sources. Also, the US is not really completely Leftist. I actually think that a few extreme Leftists are actually driving more people to figures like Trump.
The USA is also not a nation united any longer. We are becoming more and more divided along ideological lines, and the extreme rhetoric (Antifa / media mob justice) just spoils everything. Identity politics is also feeding this behaviour, as it attempts to put us all in boxes, and the apply rules to those boxes.
Kavanaugh was a strong one for me because it feeds into the radicalization of feminism, erodes men's rights and all round does more harm than good.
