"The widespread assumption that only Democrats have any agency or causal influence over American politics." This is famously known as "Murc's Law," named after a commenter at the blog Lawyers, Guns, and Money who noticed years ago the habitual assumption among the punditry that Republican misbehavior can only be caused by Democrats. Do Republicans reject climate science? Must be because Democrats failed to persuade them! Did Republicans pass unpopular tax cuts for the rich? Must be that Democrats didn't do enough to guide them to better choices! Do Republicans keep voting for lunatics and fascists? It must be the fault of Democrats for being mean to them! Even Donald Trump's election was widely blamed on Democrats — who voted against him, to be clear — on the bizarre grounds that Barack Obama should have rolled over and just let Mitt Romney win in 2012.
We're about to return to a Beltway narrative in which nothing Republicans do is actually their fault: It is somehow all because Democrats have failed to manage them properly and are way too mean.
