I'd be interested in hearing Bernstein define "malignant presidency." The man is a word merchant who I think is following the dampened footsteps of his old boss at WAPO, Ben Bradlee. Bradlee loved to refer to those whom he disliked as "retromingent." The term is scientific, describing a characteristic of cats, creatures who urinate to the rear. It's meaningless as a mode of political debate, but it apparently sounded neat to Bradlee. He used it constantly. So now Bernstein has settled on "malignant." I rather think Obama presided over a government with malignant tendencies, i.e., uncontrolled growth. So, if anything, Trump is a surgeon trying to remove malignancies before they metastasize. Maybe Bernstein should look that word up.
