Of course many of us cannot understand Trump and his policies and indeed his actual vision.
Just in the same way as many of us cannot understand Farage and Reform.
Naturally, it doesn’t make “us” right and “them” wrong, but it’s hard for people like myself, who are centre-left, to understand the ethos of those, who appear to be very narrow in their outlook, blaming every country and its inhabitants for their own countries failure.
IMO Trump is a very dangerous man as he is incredibly reactive and doesn’t appear to think things through. Like Farage, he says all the things his supporters want to hear.
