What Romney does not discuss are the political issues. Many are saying that Trump’s ascendancy is the beginning of the end of the Republican party. People are tired of voting against their interests. Sure Trump appeals to the bigotry of working class whites, and he is a bit trigger happy in his approach to foreign relations. However, he is in favor of Social Security, Medicare and Planned Parenthood. He opposes the TPP. He thinks health insurance and pharmaceutical companies make too much money. For all his talk against the ACA, he still favors mandatory health insurance. I personally find Trump to be loathsome, but in some ways he is closer in his views to Sanders than to Clinton. Here is an article which gives the best analysis I have seen of the Trump phenomenon.
