When a country gets an authoritarian leader such as Trump, his position will always be dependent on apologists that continually excuse and normalize his behaviour to the rest of the population. And I don't even think these apologists believed they would ever have to excuse such a level of racist, bigoted and misogynistic behaviour.
At the latest Trump rally, normal citizens were shouting "send her back!" almost as a scene from the 30's in Germany and Italy. These are people that most likely would have been offended by this behaviour just three years ago. But it's a slippery slope towards radicalism and the apologists are the ones who enable it.
