I watched the video recording of the rally in Panama City shortly after reading the El Paso killer’s so-called manifesto. It is a document littered with phrases and rhetorical devices injected into mainstream discourse by the president and his supporters—talk of a “Hispanic invasion,” accusations that Democrats support “open borders,” and the like. As Trump faces the possibility that he will lose the presidency next year, he may become more enraged, and more willing to deploy the rhetoric of violence as a way to keep his followers properly motivated. The Panama City speech was an important moment in Trump’s ongoing effort to make the American presidency a vehicle in the cause of marginalizing and frightening racial minorities; the killings are a possible (and predictable) consequence of such rhetoric.
