Florida Governor Ron DeSantis has announced that he will challenge Trump for the Republican nomination for president. DeSantis’s personality presents an ample contrast to Trump’s. But the two were cast in the same mold. DeSantis, in his own way, is no less mean-spirited, hypocritical, opportunistic, self-serving, and repulsive than Trump. Like Trump, he has a hole in his brain where in the case of most people humanity resides. It’s a measure of the degradation of Republicans that Trump and DeSantis are leading their pack.
