"in the 1960s, [there was certainty] that Americans would never consent to give up their big-government perks. And yet, somehow, alongside the ordinary tacking of American political preference between Democrats and Republicans, conservatism continues to thrive. That’s because power begets power: Democrats can be counted on to compromise with conservative nuttiness, and the media can be counted on to normalize it. And it’s because there will always be millions of Americans who are terrified of social progress and of dispossession from whatever slight purchase on psychological security they’ve been able to maintain in a frightening world. And because there will always be powerful economic actors for whom exploiting such fear, uncertainty and doubt pays (and pays, and pays).
Conservatism is not getting crazier, and it’s not going away, either. It’s just getting more powerful. That’s a fact that a reality-based liberal just has to accept – and, from it, draw strength for the fight."
