This proves that West Virgina, Kentucky, Oklahoma, Arkansas and Florida are the natural base of the progressive left, not the places Democrats have been jerking off to recently (Colorado, Virginia, etc.)
Not necessarily. Many of these people don't want help.
Sure they do. And many of them had been voting Democratic their entire lives and still weren't seeing their conditions improve. If neither of the parties are perceived to be protective of their financial interests, it is reasonable that they might vote on cultural or religious interests instead.
Obamacare provided healthcare to hundreds of thousands of people in coal country, many of whom never had it before. How did that go over again? Let's not pretend Democrats do nothing for the poor and spend all their time drafting hate crime laws for transgender feminists. The reason these voters switched was because they began to prioritize social/religious/cultural issues.
However, the socially conservative populist voting bloc that used to be so influential is rapidly diminishing, being replaced with generic right wingers who have bought into the GOP's economic agenda as well.
