- people who had spent a lot of time in authoritarian dictatorships and recognized his personality in the dictators of those countries.
- people who are familiar with history, and saw that he mirrored the personalities of historical dictators.
- people who are familiar with cluster B personality disorders, who correctly recognized his narcissistic psychopathy.
- people who were close to him, like his family, who warned us about how he treats people close to him.
- people who went into business with him, who were unilaterally screwed over by his business practices.
- Hillary Clinton.
Listening to any of these people, or even better, all of these people, would have saved us from this whole mess.
Notably, all of these people are saying the same things today, and he's still the front runner of the Republican party. So really, the problem isn't Trump anymore, it's that a lot of people actually want a dictatorship, because they perceive they can use it to their political advantage. That's where we are now. There are no more excuses about who the man is. Trump wants to be a dictator, and Republicans like that idea. There's no more assumed good faith to be had here.
