Washington DC is suddenly full of anonymous Democratic insiders who are dishing dirt on Joe Biden's parlous mental state. The New York Times rounds up a lot of them for a long story today, and if you read carefully one of the recurrent themes is that Biden's mental state has fallen off a cliff in just the last few months:
People in the room with him more recently said that the lapses seemed to be growing more frequent, more pronounced and more worrisome.... Last week’s debate prompted some around him to express concern that the decline had accelerated lately.... This person said Mr. Biden had shown a “sharp decline” since a meeting only weeks earlier.... A senior European official who was present said that there had been a noticeable decline in Mr. Biden’s physical state since the previous fall.
Politico described Biden as getting worse recently during routine briefings:
During meetings with aides who are putting together formal briefings they’ll deliver to Biden, some senior officials have at times gone to great lengths to curate the information being presented in an effort to avoid provoking a negative reaction. “It’s like, ‘You can’t include that, that will set him off,’ or ‘Put that in, he likes that,’” said one senior administration official. “It’s a Rorschach test, not a briefing. Because he is not a pleasant person to be around when he’s being briefed. It’s very difficult, and people are scared shitless of him.”
Angry outbursts are a bad sign. All of this is a bad sign. And it might explain why nobody talked about it until now: no one is going to tattle about occasional lapses, and it may be that Biden hasn't shown any serious cognitive issues until relatively recently.
In any case, if this is right it means things are going to get even worse in fairly short order. Unfortunately, Biden himself doesn't see it. When you start to lose your faculties, the first thing to go is your ability to recognize that you're losing your faculties.
