Bear with me for a second. Everyone is supposed to be ecstatic about the inauguration. But on all social media the response of even centrists was to relate to the Bernie meme. The guy is a soc dem at best but let's be real here: the fact that there is so much grass roots support for him when even his milquetoast policies are roundly attacked on the major networks tells us something about how people are feeling when they're being told to celebrate the best day ever. People are in despair. They can't join in on the celebrations because they're in a pandemic. It's insane. And every centrist in the country knows it.
Problem is there’s sentiment not structure and without structure you’re SoL.
Or rather the situation is even more dire, the right has all the sentiment and zero structure (see: the riot in the capitol) but the left has a rising sentiment and is still trapped in by the structure of liberal electoralism which dissipates the sentiment (see: virtually every left figurehead buying into the “Dems are the lesser evil” lie). The far right has properly radicalized and now exists outside the structure of bourgeois democracy but they’re left afloat with no direction because they have no leadership and no true material politics. They’re just furious and know the standard institutions are bullshit. The left has a rising tide of dissatisfaction with the institutions of liberalism but has not fully careened off into radicalization writ large because they haven’t had a figure lead them there like Trump has for the right. Sanders’ attacks on the status quo were left for private corporations and specific political figures, not democratic institutions at large. People might be pissed and dissatisfied with where this ended up per your point about the Sanders meme, but they don’t have a direction to face that anger and will likely fall in line behind their favored media personality’s opinion toward anger at Mitch, anger at Biden but not democrats writ large, or even anger at Democrats but only “current” democrats and actually the Supreme Court is a good thing sweaty.
