I think it's simpler than that. Conservatism, at its core, has always been a purely reactionary opposition to liberal and progressive politics. In the modern era, it has felt the need to wrap itself in something resembling a positive ideology which presents thinly falsifiable policy positions, regardless of how narrow and mutable those ideological boundaries might be. Because until recently, abject, reactionary nihilism has been seen as a losing position.
Trump has freed conservatives from that burden. No longer do they need to create and defend any flimsy intellectual basis for their reactionary stances - Trump has presented a completely liturgical basis for conservative nihilism, and in doing so, he has freed millions of anti-intellectual CHUDS from the burden of thinking, and they love him for it.
