Here's English/American Catholic Andrew Sullivan's response to that:

"In Britain, where the polls did not pick up the latent support for withdrawal from the European Union, a new prime minister is now navigating a new social contract with the indigenous middle and working classes forged by fear of immigration and globalization. In the U.S., the movement — built on anti-political politics, economic disruption, and anti-immigration fears — had something else, far more lethal, in its bag of tricks: a supremely talented demagogue who created an authoritarian cult with unapologetically neo-fascist rhetoric. Britain is reeling toward a slow economic slide. America has now jumped off a constitutional cliff. It will never be the same country again. Like Brexit, this changes the core nature of this country permanently."
