Are all republicans rich that they do not need social security or medicare, are the people in Appalachia well off, do they vote republican?

Aren't some republicans on welfare and on the so-called Obamacare? Why are these people voting against their own interest? I keep asking myself, how could so many people elect a person who does not care about them!

Look at the people trump is nominating for his cabinet, he is not draining the swamp, he is emboldening the swamp. If people are not scared yet, I have no idea when they will get scared. Unless he has them mesmerised and his bus tour will galvanise them to support him even more.
