I regret to report the economic anxiety theory of Trumpism is back

The question of why Donald Trump manages to maintain such a grip on the Republican base, to the point where he can remain a nationally viable candidate despite all of his misdeeds and legal woes, is one of the most important issues in American politics. It’s a subject that has been explored extensively, with the best evidence converging on the same general story: Trump is the avatar of a kind of resentful reactionary politics, one uncomfortable with a changing America, that defines the worldview of a plurality (if not a majority) of the GOP faithful.
