Rural resentment of American urban elites is a theme that goes back to Jefferson’s time. The most dramatic example of it, of course, was the Populist movement of the 1890s. Is it in any way comparable to what we see today?
No. William Jennings Bryan was genuinely interested in improving the lot of rural residents. He had a policy platform that was designed to do exactly that. He never preached resentment as an end in itself.
Trump, on the other hand, has no plan to improve the lives of the people he claims to represent. Fortunately for him, they don’t seem to mind; for example, his China tariffs resulted in retaliation and cost American farmers one of their best markets, but they support him anyway, because he is their retribution.
