Mark Levin, despite his tendency to shout at his television audience, is often a formidable critic of the contemporary American left. He is, though, an exemplar of the now pandemical affliction of much of the American political intelligentsia, left and right, to impute absurdly extreme faults to their opponents.

In his justified contempt for the Biden regime and most Democrats, Mr. Levin has demonized the Democratic Party as an instrument of almost systemic evil since before the Civil War.
