Writing in National Review, David French sets up a straw man - Trump caused Brexit - and then knocks it over. The notion is, of course, nonsense as I'm sure Trump would be the first to admit.
What is not nonsense is that the same sort of factors that caused Brexit are also responsible for Trump winning the GOP nomination. Trump didn't cause Brexit; populism and anti-global nationalism caused both the Brexit passage and Trump's primary win.
French is correct that the circumstances facing the U.K. and U.S. are different, but the angry feelings in the demos are more similar than different. People in both countries see out-of-touch elites pursuing their own agendas without considering the electorate's desires, and vast swathes of both populations left behind by globalism.
