“Sanewashing”
That is an interesting new term, and describes what the MSM has done, for years, of liberal craziness.
Conservatives used to be the intellectual party with the smart egg-heads in the 1980s-1990s (Milton Friedman, Sowell, Krauthammer, Irving Kristol, WFB Jr., George Will, William Safire, etc.). These used to combat the left-wing intellectuals effectively, beating them in rhetoric. Then, new ideas and new lingo used to come from the right. Now, the intellectuals have deserted the MAGA movement, and the left has gained intellectual ascendancy.
