The Trump resentfuls are mostly found in small towns and rural areas, and among older people, non-college graduates, groups once dependent on manufacturing and mining jobs, and social conservatives and white Christians.
Trump’s resentfulls have a sense of displacement in a country they once dominated. Immigrants, minorities, non-Christians, even atheists have taken center stage, forcing them to the margins of American life.
Trump’s resentfuls believe that the big-city elites, the professionals, and the government - before Trump came along - all failed to help them achieve their share of the American Dream. They resent professionals and liberals telling them how to live, calling them racists, or limiting their freedoms - e.g. to buy multiple guns or go about maskless during our present pandemic. "President Trump was at his best when he ignored the experts and went his own way,” resentfuls say.
Many of Trump’s resentful feel they are "being treated unjustly, unfairly, or disrespectfully."
The appearance of Trump and discovery of like-minded people - via the Internet and the person-to-person contacts of smaller towns - help overcome feelings of powerlessness. Feeling more powerful, some "people merely want a remedy for the injustice they have experienced. But others - typically those who experience disrespect - want more than redress; they want revenge.
