i've talked to left and right wingers in person about this and most seem to agree with this concept or contributed to it. at the vaguest level it's perceived as two groups, the neoliberals/neocons and the populists. the populists have a left (berniecrat, demsoc) and right (trumpian, nazbol-lite) wing. the neos are all the old guard repubs (mitch) and centrist/corporatecrats. at their most basic understanding of this they believe the populists are trying to help the people while the neos only care about the markets. obviously this struggle is being heavily catalyzed by the 2k checks.
The left populists have the same problem. They keep coming groveling back to the Biden centrists, tails tucked between their legs
Yeah I can't disagree. They all very loudly campaigned for that piece of shit and they're extremely hesitant to break ranks on anything even though Biden would 100% rather work with neocons.
