I haven't tried your link but there are significant parallels between Trump and Berlusconi, who was re-elected PM of Italy more than once.
I think he got his comeuppance over legal/ monetary conflicts.

Right now I'm watching an interesting old flick: "A Face in the Crowd". Demagoguery is nothing new in American politics. Just that I don't have the good feeling I used to when I could assure my foreign friends that "political jokes are fine, as long as they don't get elected."
