It doesn’t matter who was President, if he’s not a Democrat, he would be called racist, divisive, nazi, hypocrite, etc, etc., and everything else we are hearing now.
In fact, on many issues, Trump is not very conservative. Nonetheless, the Left doesn’t care
The reason is - they have achieved more and more power and influence: certainly throughout government, media, entertainment, academia and business (particularly tech and social media).
Their bureaucratic political machinery is in place to oppose ANYONE who is not Democrat/Leftist. They would spray a fire-hose of invective at anyone from the GOP.
The Trump candidacy then presidency represents the possible demise of the professional political class. The “all knowing” class that’s determined to run our lives without ever having had any experience in “life”. Basically its government by graduate student bull sessions (There are stories the Slick William WH was exactly this way!). Government (and voting!). They have no understanding of how things work, don’t want to take the time to learn & don’t think they need to. There are GOP’ers & of course Rats of this mind set. GOP’ers approach it with a conservative hue & rhetoric Rats from the left but they want to go to the same spot.
