Being atheist/agnostic doesn't protect people from irrational political opinions.

You are talking about religious people thinking they have the "correct" political beliefs, but I want to go farther and say this:
When I was in grad school and heard a fellow activist refer to something as being--or not being--"politically correct", I thought he must be joking till I noticed the dead-serious look on his face!
Imagine that anyone with any understanding of history or politics could be so simple-minded as to think that our understanding of politics can be reduced to a kind of calculus! First, there are unknown causes; second, even with known causes, science and mathematics are usually incapable of giving very certain predictions to any but a few variables of a system as complex as human society*; and third, even if we we had a complete knowledge of the causes and complete ability to predict, what values would we try to advance in our actions?

*There are some conserved quantities, such as energy or angular momentum, and there may be empirical laws or trends which are useful besides those originating from physics.

I believe they feel they got theirs so why care about anyone else, especially since they are A) of the mindset that if you are poor, sick, unemployed you did something to deserve it and God is punishing you and B) if you were a true Christian God would reward you with all the income and good health you need.

Can you be a bit more specific? which ideas are you trying to explain? Which ideas do they espouse? You wrote a whole paragraph about nothing. All I garnered is that you have a degree in history with some stress on political science. Let me ask - are you just regergitating the opinions of your professors?

Fox News is Trump's ally. Faux News.

Regardless of who gets elected they often say "It's God's Will, so the right candidate won"

Most Evangelicals in America get their ideas both from their bible and from the preacher. Some go to church 3 times a week and hear this preacher telling them exactly how it is. This guy doesn't even know his bible, let alone know anything at all about documents of our government.
With everything going on there is a new store in my small town right now. They claim to be based on the 2nd Amendment and appear to want you to buy guns and flags. You can do what you want to but I don't see anything here that is based upon reason. Just more Trump supporters that want to worship his ass. As for me, I only have 1 gun and I have no desire to fly an American flag. Maybe I don't see much Patriotism going on here.

I don't know why you would be amazed, that is why they are called believers. They have the faith (in whatever the fuck they want to believe in) and objective evidence can be rejected because their mother and the preacher told them so. When I was presented with the idea of intersubjective belief I gained a better understanding of human nature. This and his follow up Homo Deus made me a believer: [goodreads.com]

We have a lot of christian radio here in SE OHIO and west virginia and the things I hear on the radio are mind dropping? Did you know that the Jews killed Jesus? I'll be damned if that is not what I heard last fall on a small station. I emailed a friend who is Jewish and he said that it is common. It is almost as if those christians want to hate and are not happy unless they are.

I call what you described above willful ignorance on the part of the religious screwballs, they know they are wrong but will not come to terms with that though.

Well, as far as my parents are concerned, Fox News is the bearer of the Ark of the Political Covenant. It's on 24/7 at their tabernacle.
