As is my occasional wont, I have decided to post a comment made under a previous comment, in this case anonymously:
It's an interesting one, isn't it?
The areas that swung Brexit, not the ones in the South that would have voted for it anyway, had little or no immigration but had had lots of jobs sent abroad by globalisation, including the EU.
The areas that gave Trump his thumping great win didn't have much in the way of a Latino population: 5.3% in Iowa, 6.2% in Wisconsin, a mere 3.3% in Ohio, 6.1% in Pennsylvania.
But they'd had lots of jobs sent abroad by globalisation, including the Clintons' NAFTA.
