How Has The Radical Right Evolved Under Trump?

sarahf (Sarah Frostenson, politics editor): Last Wednesday, the U.S. Capitol was attacked by a mob of President Trump’s supporters, many of whom had very explicit and not so explicit ties to right-wing extremism in the U.S. There are reports now, too, that there could be subsequent attacks in state capitals this weekend. President Trump’s time in office has undoubtedly had a mainstreaming effect on right-wing extremism, too, with as many as 20 percent of Americans saying they supported the rioters. But as we also know, much of this predates Trump, too. Right-wing extremism has a long, sordid history in the U.S.
ameliatd (Amelia Thomson-DeVeaux, senior writer): Well, the first and most obvious thing is that Trump has spoken directly to right-wing extremists. That is to say, using their language, condoning previous armed protests at government buildings and explicitly calling on them to support and protect him. And that, probably unsurprisingly, has emboldened right-wing extremists and made their extremism seem — well, less extreme.
That goes for a wide array of extremists in the U.S., too. I’m thinking, of course, about Trump’s comment after the white supremacist violence in Charlottesville, Virginia, when he said there were “very fine people on both sides.” But Trump has also encouraged white Christian nationalists, anti-government extremists and other groups and individuals that I certainly never thought I’d hear a president expressing sympathy or support for.

maggie.koerth (Maggie Koerth, senior science writer): I’ve been talking to experts about this all week, and I think it’s really interesting how even the academics who study this stuff are kind of arguing over the role class plays in it. People like Christian Davenport at the University of Michigan have argued that we should understand that all of this is happening in the context of decades of growing income inequality and political stagnation. In other words, he contends that there are legitimate reasons to be angry at and mistrust the government. But it also seems like this crowd was not even close to being uniformly working class and probably contained people from a range of different backgrounds. And that’s why I liked one of the points Joseph Uscinski at the University of Miami made: We might be seeing a coalescing of two groups: the people who have been actually hurt by that inequality and are angry about it AND the people who are doing pretty well but who feel like somebody might come and take that away. And, of course, both those positions can dovetail very easily into racial animus and white supremacy.
