Victor Davis Hanson of National Review Online explores cognitive problems plaguing former Vice President Joe Biden as he campaigns for the White House.

Joe Biden is tragically suffering a mental eclipse and sliding away at a geometric rate. Understandably, his handlers have kept him out of sight. He stays off the campaign trail on the pretext of the virus and his age-related susceptibility to COVID-19 morbidity.

I say “pretext” without apology. Quarantine should not have otherwise stopped Biden over the past three months from doing daily interviews, speeches, and meetings. But each occasion, however scripted, rehearsed, and canned, would only have offered further daily proof that Biden is cognitively unable to be president or indeed to hold any office.

Often Biden cannot finish a sentence. Names are vague eddies in his mind’s river of forgetfulness. He is in a far more dire mental state than a physically failing FDR was in his 1944 campaign for a fourth term.

The earlier career of a healthy Biden illustrates that he was not especially sharp even when in control of most of his faculties. We recall the former sane/nutty Biden of Neal Kinnock plagiarism, his “put y’all in chains” demagoguery, the studied racism of Biden’s riffs about a “clean” and well-spoken Obama, and the sane/insane Corn Pop stories. All are the trademark of a once fool Joe Biden, who was at least alert when compared with his current catalepsy. If Donald Trump can be ungrammatical, Biden is agrammatical — he simply streams together half-thoughts without syntax and then abandons the sentence entirely.

If Trump repeats vocabulary, Biden increasingly searches for words, any noun, whatever its irrelevance to the point he is making. Biden seems to suffer dyscognitive seizures, in which for moments he has no idea what he is doing or saying or where he is — a tragic, nearly epileptic condition.
