It’s fanciful to claim that democrats don’t understand what they’re doing. There is no way they don’t realize that republicans have no interest in bipartisanship, and the only explanation I can see is that they’re intentionally easing US into fascism.
They’re basically keeping people passive while republicans dismantle the vestiges of a democratic process and they’re also using the time to beef up and militarize the police. When republicans get in power in 2024 they’ll have all the tools need.
I think the proclaimed democratic collapse pertains to the “imperialism turned inwards” aspect of fascism. USA is running out colonies to exploit. Contradictions of capitalism are mounting resulting in severe deterioriarions in the material conditions of the working class. This could lead to even more violent suppression of the working class expressing their grievances.
