I have been a student (and colleague) of George Lakoff for some time and have used his ideas extensively. In particular, my latest coauthored book relies heavily on his research and ideas.

Here is the link: http://www.truth-out.org/buzzflash/commentary/george-lakoff-embedded-nar...

His explanation for Trump's popularity is the best I have seen. here's a taste:

Donald Trump is winning Republican presidential primaries at such a great rate that he seems likely to become the next Republican presidential nominee and perhaps the next president. Democrats have little understanding of why he is winning — and winning handily, and even many Republicans don't see him as a Republican and are trying to stop him, but don't know how. There are various theories: People are angry and he speaks to their anger. People don't think much of Congress and want a non-politician. Both may be true. But why? What are the details? And Why Trump?

Many people are mystified. He seems to have come out of nowhere. His positions on issues don't fit a common mold.

He likes Planned Parenthood, Social Security, and Medicare, which are not standard Republican positions. Republicans hate eminent domain (the taking of private property by the government) and love the Trans-Pacific Partnership (the TPP trade deal), but he has the opposite views on both. He is not religious and scorns religious practices, yet the Evangelicals (that is, the white Evangelicals) love him. He thinks health insurance and pharmaceutical companies, as well as military contractors, are making too much profit and wants to change that. He insults major voting groups, e.g., Latinos, when most Republicans are trying to court them. He wants to deport 11 million immigrants without papers and thinks he can. He wants to stop all Muslims from entering the country. What is going on?

The answer requires a bit of background not discussed in the media to date.

The last statement is an understatement if I ever saw one.

I'll skip over his family model for American politics but if you are unfamiliar with it please read about it in the link.

The analysis of causation is crucial:

Direct vs. Systemic Causation

Direct causation is dealing with a problem via direct action. Systemic causation recognizes that many problems arise from the system they are in and must be dealt with via systemic causation. Systemic causation has four versions: A chain of direct causes. Interacting direct causes (or chains of direct causes). Feedback loops. And probabilistic causes. Systemic causation in global warming explains why global warming over the Pacific can produce huge snowstorms in Washington DC: masses of highly energized water molecules evaporate over the Pacific, blow to the Northeast and over the North Pole and come down in winter over the East coast and parts of the Midwest as masses of snow. Systemic causation has chains of direct causes, interacting causes, feedback loops, and probabilistic causes — often combined.

Direct causation is easy to understand, and appears to be represented in the grammars of all languages around the world. Systemic causation is more complex and is not represented in the grammar of any language. It just has to be learned.

Empirical research has shown that conservatives tend to reason with direct causation and that progressives have a much easier time reasoning with systemic causation. The reason is thought to be that, in the strict father model, the father expects the child or spouse to respond directly to an order and that refusal should be punished as swiftly and directly as possible.

Many of Trump’s policy proposals are framed in terms of direct causation.

Conservatives are not the only ones who are confused about causal relations in the real world. There are plenty on the left who are also. My diaries on Kos exposed a lot of that.

The punch line is beautiful:

Biconceptuals

There is no middle in American politics. There are moderates, but there is no ideology of the moderate, no single ideology that all moderates agree on. A moderate conservative has some progressive positions on issues, though they vary from person to person. Similarly, a moderate progressive has some conservative positions on issues, again varying from person to person. In short, moderates have both political moral worldviews, but mostly use one of them. Those two moral worldviews in general contradict each other. How can they reside in the same brain at the same time?

Both are characterized in the brain by neural circuitry. They are linked by a commonplace circuit: mutual inhibition. When one is turned on the other is turned off; when one is strengthened, the other is weakened. What turns them on or off? Language that fits that worldview activates that worldview, strengthening it, while turning off the other worldview and weakening it. The more Trump’s views are discussed in the media, the more they are activated and the stronger they get, both in the minds of hardcore conservatives and in the minds of moderate progressives.

This is true even if you are attacking Trump’s views. The reason is that negating a frame activates that frame, as I pointed out in the book Don’t Think of an Elephant! It doesn't matter if you are promoting Trump or attacking Trump, you are helping Trump.

A good example of Trump winning with progressive biconceptuals includes certain unionized workers. Many union members are strict fathers at home or in their private life. They believe in “traditional family values” — a conservative code word — and they may identify with winners.

Why Has Trump Been Winning in the Republican Primaries?

Look at all the conservatives groups he appeals to!

The Democratic Party has not been taking seriously many of the reasons for Trump’s support and the range of that support. And the media has not been discussing many of the reasons for Trump’s support. That needs to change.

By the way. From Lakoff's approach Bernie is right on the mark and that is why he does so well.
