You can't really put that into a very short slogan like "Make America Great Again" and "Illegals are stealing your way of life". Simplistic hate and fear is what those people want to hear, seems to me.
I've heard that very message said many times (that Democratic policies are better for them). They don't seem to want to listen. They vote for people that put in a tax "reform" that boldly gave a huge fucking raise to the ultra-rich, and then Paul Ryan tells a fantastic story about some single Mom who will save enough to pay her 10 dollar (at the time) Netflix bill. They piss on them and don't bother to call it rain, and get their votes back in return.
In short, I don't blame the Democrats for not reaching rural voters. They don't have a choice but to keep trying though.
