Agreed. The dems need to get some of the old white people vote in the mid east states. They aren't going to vote for socialists. They are scared. They are scared of Muslims; scared of losing their jobs; scared of immigrants; scared of losing their culture; and etc. We need a sliver of them to return to the democratic party.
It's probably easier and quicker to wait for them to die, than it is to get enough of them to change.
That being the case, the real priority is to inoculate their children against the same fear-driven conservatism.
The jobs, the comfortable unquestioned racism, and the bolted-on religion are gone; and they are never coming back. Rural and small town America is massively overpopulated; and the only solution is mass migration to the cities, where there is at least the possibility that jobs will be available. Going back to the 1950s boom-times is simply impossible - the world has changed, largely for the better, and it's never going to change back, so the people need to change with it, or get trampled underfoot.
The only thing that could possibly soften the blow is socialism - taxing the people in the cities to provide handouts for the rural and small town folks (of course, these can be disguised as 'subsidies' and 'incentives' to generate busywork and salve their pride). It's not a solution, but it will perhaps mitigate some of the worst effects of the problem. Except that it's the one thing they are adamant that they will not allow. Which makes it hard to be even slightly sympathetic to their plight.
At the end of the day, these people are scared and angry, because they have been systematically lied to. They were told all their lives that hard work, self reliance, and support for a rigid social structure would result in prosperity. But this is neo-Marxism - The idea that hard work is always rewarded is just a re-wording of the idiotic labour theory of value. Hard work doesn't get you wealthy, it gets you a bad back. Self reliance makes you weak, because you refuse to accept the help you need - or to allow it to be offered to your neighbour. And the rigid social structure - belief in God, and the innate superiority of the white Christian American over all others - sows the seeds of a destructive rage, when it turns out that neither of those things are actually real.
You can no more get these people to vote Democrat than you could get the high priests to stop sacrificing virgins, and start running away from the lava flow. They know that what they are doing isn't working; But they conclude that this means they haven't done enough of it yet.
