Mostly talking about stuff like breadtubers, chapo, and media personalities like that, I can kind of tell why people like Bernie and Jezza where they're at. Is it the added wealth being a popular media personality gives you, the need to give a consistent product, the need to appeal to a wide breadth of people, and so on?
edit: also props to Brett at RevLeft for continuing to radicalise himself as the show has gone on
In the 1930s, CPUSA had as many official members as the DSA do now (and the US population was less than half of today). That put a lot of pressure on FDR to work with more "moderate" figures like Walter Reuther, future head of the UAW who Khrushchev described as "somebody we would have hung in 1917" and would be denounced as a radical in 2020.
