As I travel Europe, my friends here are mystified. How does Trump say these things and still get nearly half the people behind him? Europeans get the same mainstream news that we all get worldwide, but there is something about the U.S. that is invisible to them — namely, they do not see the 24/7 blanket of right-wing talk radio in all 50 states (in addition to Fox news). Drive across the U.S. and at every point you can pull in 5 or 6 right-wing radio channels (not to mention conservative religious channels) all day long that have said for years said the same kind of things that Trump is saying now. It is that invisible blanket that has made this kind of talk normative in a way that is perhaps not quite fathomed by those outside of the U.S.
At least that’s one explanation. I welcome others.
