It depends who the Republicans and Democrats are. Republican Voters fell in love - Establishment Republicans fell in line. Republican Officials all talked about how terrible Trump was and would be but still get on their knees when it’s time.
Democratic Voters fall in love, with Bernie and AOC and their guy. Establishment Democrats tell them to get in line… Well, the Voters either do or don’t show up.
So, you’re correct that the original subversion was true but it also depends on who any individual commenter references as “The Dems” and “The Repubs” which you can always shift to suit your needs.
The Republican party pretends they’re wagging the dog but they don’t even have a leash.
