I kinda disagree with her characterization of the whole "coup attempt" thing, which she presents as "totally fabricated", "without evidence", etc. Which is true - some people sitting in a room wargaming isn't a coup or a plot to take over the country in and of itself. It's not a crime to do that. But the steelman "extremist" (her word) argument is that the publication of the WaPo essay (and Hillary Clinton saying Biden "should not concede under any circumstances", and this essay itself, etc) represents the elite using free speech to establish a Schelling point, or common knowledge, of how to dispute the election. By now anyone with any political awareness knows, and knows that anyone-with-any-political-awareness knows, that the election results won't be known for weeks or months after the election. And that mail-in ballots are going to decide the election. And that Trump is suppressing votes. It's a kind of manufacturing of consent for the intellectual elite who hate Trump. But to them this sort of thing is totally invisible - that kind of speech is good and important for democracy, because it establishes a collective template for coordination-free cooperation to ensure Trump is not reelected. It's the other kind of speech that is bad.
