I guess the patsocs got it all wrong. If you wanna do maga-communism you gotta do it as a socdem who maintains a reputation for being a clean outsider to the establishment.

Basically the same reasons some of them went for Bernie. They recognise that the 2 parties are trash and want outsiders that are clean of the establishment corruption that they intuitively recognise. But they can't tell the difference about which outsider is lying.
