Rhetoric about scapegoats that distract people from the real causes of their issues, a cult of personality, and lots of money. Additionally, a lot of his voters thought he started to expose the truth behind how things actually run in the government instead of seeing how he is playing them for fools just as much (or more than) other politicians. Mostly though, it’s the money.
I’m not who you asked, but I often think of supression tactics against forms of free speech used in the US that some countries in the EU do less. Not all of them (UK online speech policing and arrests as a counterexample), but voter supression, union busting, and law enforcement response to protests have been handled in various countries in ways I consider more free for the citizens.
TLDR: Intimidation tactics and biased response happens less in other countries.
