"Gosh, why wasn't Trump Hitler or a Nazi the first time?"
I keep seeing this ridiculous question.
First, Trump is not Hitler. There are many disturbing parallels between now and 1930's Germany, but Trump is not Hitler. Again: Trump is not Hitler. The fact that the people nearest him are fascists and that he is essentially a de facto fascist does not make him Hitler. A fascist is not necessarily a Nazi.
To answer the question:
1. He hired staffers who were not willing to put Trump over the office. He wants pure, blind loyalty, and their loyalty was to the Constitution. That definitely will not be the case this time. He will specifically and aggressively surround himself with sycophants exclusively.
2. He did not have a specific set of plans going into his presidency. He sure will this time around. They'll hit the ground hard on Day One, and here comes Project 2025 and Theocracy Lite™. We will see an early and historic flurry of activity from the White House.
3. Perhaps most importantly, he has a breathtakingly compliant Supreme Court that has paved the way for him by making him immune. He has no legal or ethical restrictions this time around. He will be the first American President with nothing holding him back.
It's a stupid, insulting, boring, ridiculous question, but now you have your answers. You're welcome.
