Musk’s current obsession, as Greg Sargent observes in The New Republic, is the “great replacement,” a far-right conspiracy theory that liberal elites in the United States are deliberately opening the southern border to nonwhite immigration from Mexico, South and Central America in order to replace the nation’s white majority and secure permanent control of its political institutions.

On X, Musk recently pinned a post to a slickly produced video that purports to expose a “Democrat open borders plan to entrench single-party rule,” in which Democrats shepherd millions of people into the United States and “keep them in the country at all costs.” Musk says, “This is actually happening!” The video had, at the time of this writing, well over 50 million views.
