Politics expert, please help analyse the phenomenon of Trump's paradise: Oklahoma

This is what I found on Oklahoma support for Trump:

The Republican Party Still is Strong
On the national stage, the Republicans are in disarray. Their candidates and their congressional representatives are useless as tits on a boar. If they did not so completely control so many local and state offices, I would agree that the Grand Old Party is dead in the water. The truth is, the southern coalition that they built is largely intact. They are strong in other states as well. And they still hate Democrats and other "socialists." All they really need, to become viable again, are a few strong candidates. Let us hope nobody of consequence emerges.

Fear and ignorance are Trump's bread and butter. Oklahoma is full of Christians. See?

Democrats tend to be supported more on the coasts and in large cities. Republicans tend to be supported more in inland and rural areas.

Oklahoma is inland, and what cities there are, are not particularly large. It is also close to Texas, which is unrepentantly (perhaps even belligerently) conservative despite having large coastal cities (Texans have never stopped being "rough and tumble" cowboys).

I would imagine that a poll that focused on another mostly-rural inland state (say Kansas) would get a similar result.

I noticed something on that page: "Donald Trump has led a movement across the nation calling for improving the economy, strengthening our military and reforming health care and immigration laws". Could you please tell me what is the problem with health care in US exactly? I followed the pre-election debates of governor Romney and president Obama in 2012 and one of the problems that Mr. Romney emphasized on was the health care problem and now I think there must be really something.

I thought more about your post" religion and fear" and I looked deeper and closer into people who live around me and all over the world and I think for very many people you are right but not all of them.

Thank you for your interest. In my observations, Trump supporters are afraid of Blacks, Hispanics, Immigrants, Muslims, Russians, Chinese, Iranians, North Koreans and all Middle Eastern People. They are also afraid of imminent economic collapse, terrorist attacks, loss of "American" culture through dilution, and invasion.
Now everyone is afraid to some degree, but Trump supporters seem to be willing to compromise our ideals for relief. Trump himself has said that he is the only one who can protect them. He plays upon our insecurities and seeks to exploit them.

Russians? They best line up behind their leader.

This narcissist would claim such an idiotic thing.

No one person in the world can protect a whole country. That's simple logic.

A drowning man will grasp at a straw. Tell a fearful man you can protect him and you have him in the palm of your hand. Trump is a skillful manipulator. He knows how to work a crowd, he knows how to play the media. It's been done many times in history, the megalomaniac first stokes fear in the population and claims to be the protector or the savior. So sad that it seems to be working again, at least to degree.

But Republicans think in absolutes, good and evil.
I lost my uncle in the war of Iraq 30 years ago and I never saw him.
Wars are paid on credit cards. I think in the case of any war the final loser will be the people of both sides.
Let's vote to somebody who doesn't want war.
Love you American and wish you the best.

Republicans don't think in a certain way. Some Republicans surely think in absolutes, as do some Democrats as well as any other group you can think of. A statement like that is what prejudice is made of. The Republican party is made up of individuals and each think their own thoughts. You can state the core beliefs of the Republican party, but that still doesn't describe what all Republicans think.

Also, most are not strictly democrat or republican. I believe most cross over from one party to the next in degrees depending on the issues.
I condemn the republican party in some states in which they are trying to suppress voting. I agree with their policy to keep governments small.

Clearly and concisely stated, I agree completely. I've been a registered Republican for most of my adult life (I was briefly registered as an Independent) and I've always had points of disagreement with Republican candidates and elected officials. Sometimes more, sometimes less.

Yes, of course, I didn't mean all of them.
But some phrases like: " You're either with us or against us" divide the world into black and white.
With all my respect such statements are shallow from the former president of such a country.

They invaded Iraq under the excuse of finding WMDs.
American people paid for it. You experienced the worst financial crisis since the great depression.
I've visited Iraq and I can't even imagine worse than that.
You said they are afraid of "Blacks, Hispanics, Immigrants, Muslims, Russians, Chinese, Iranians, North Koreans and all Middle Eastern People".
Say half of the world.
I think you've got a propaganda by those Republicans rather than being under a real threat by half of the world.

The propaganda machines exist to keep the party in power or to topple the opposition. There are as many as there are political parties. They all use fear (and other tactics) to attract supporters. I personally don't think we are under any real threats at all. Any one of those countries or groups I mentioned COULD become a threat under the right set of unlikely circumstances, so the probability isn't zero, but it certainly doesn't warrant the kind of over reactions that Trump is proposing.
