I recently read someone saying the GOP has no ideology other than demonstrating they have power over people they feel threatened by. That description rang true for me.
Agreed, but I'd add that a huge motivation for the Trump GOP is deep resentment and pure hatred and jealousy of America's college-educated professional classes, and a powerful desire to make them suffer and lower them to their level of economic frustration and failure. MAGA is basically working-class white America going to war with our professional classes - lawyers, doctors, scientists, teachers, engineers, white-collar office workers and managers, people who now work online from home, and above all college professors. They literally hate all of these people because they often make more money, live in better homes and neighborhoods, live in cities that are thriving while very often their towns are dying or at best economically stagnant, and so on. And they are convinced these people are social snobs who look down on them as worthless ignorant white trash, and so they want to destroy their careers and lives as much as possible. And Trump is their instrument of revenge on these people, which is why they love him so much.
Look at DOGE firing all of these government workers and Trump 2.0 gutting and ending funding for medical and scientific research, trying to take over universities and fire professors and other academics, going after public school teachers, threatening law firms and RFK, Jr. attacking the medical establishment. It's all part of a pattern - to humble these people and "get even". The fact that they're ultimately hurting themselves and the country as a whole doesn't matter - it's just pure resentment in action. Republicans have long said they feared a class war brought on by Socialists and Marxists, but they're waging a class war right now, full force.
