This interview with Sarah Smarsh is good:

She says that the Republicans were the party that validated working class voters’ pain, even if the rest of what they said was a pack of lies and they plan to help the rich and harm the poor. The Democrats didn’t even get this far: they repeatedly ignored working class suffering while insisting the economy was good and making promises to help the “middle class” (whoever that is these days). Given the choice between one party that says “we hear your pain” and another that says “you’re too ignorant to realize things are actually going well” it’s not surprising which party got the working class votes. It’s just a shame the Republicans don’t actually plan to help these people.
Socialism isn’t even on offer these days. What Republicans consider socialist stretches all the way from communism to conservatism.
