I believe that Mississippi, for example, is overwhelmingly conservative, that they get $2 in federal funds for every federal tax dollar they contribute, and that 40% of their state budget is federal money.
They are the most extreme example. Not just in that, but also in education, income, so forth & so on.
I realize that you're invoking the purple America meme, largely true, but that doesn't explain how more affluent areas, more blue, have pounded money into the poorer areas, more red, for decades, only to find those areas as insular, backward & spiteful as they ever were. That extends across much of purple America, as well.
Maybe that has something to do with what they believe, what they teach their children to believe, and the way they process factual information that's contrary to those beliefs... apparently, the more threatening that contrary information is, the fiercer their resistance becomes.
Maybe they need to learn something from more contemplative conservatives, ones who aren't afraid to think outside of the box-
