They may well be but they're not voting for liberals or socialists no matter how much you focus on "working class issues." Politics is far more tribal (and in their cases, nativist.) A lot of leftists have a hard time accepting that because Marx says it shouldn't be that way.

Never say never? The Founders feared class warfare & envisioned a Republic with an unengaged middle class chasing the American Dream. The death of the middle class is changing all of that. Are you talking to MAGA & by that I mean the farmer in the field or the shopkeeper in Custer SD?

Lef's just say it was all on the menu. The point is, you're talking about something you have no expenrience with or rel knowledge about.
