Unless one was a Bircher or another fringe conservative, an undercurrent of distaste what all it was: unspoken in public, only hinted at in think-tank papers in the form of theoretical oppositions to Keynesianism. Even during the 1980s, Reagan and Bush couldn’t come out against the New Deal, because many GOP voters were still old enough to have directly benefited from it.
As with opposition to fascism, good feelings about FDR and the New Deal have died out of living memory and created an opening where right-wingers could afford to openly go against what was once established public sentiment.
I should have qualified my statement above in that all this will seem weird to people under age 65 who are educated and know the real history. If one doesn’t have a proper education, one might buy into EmptyG’s contention that the New Deal was the first step in a sinister (((Commie))) plot that’s culminating with Biden.
