He’s been showing these signs for 20 years. Slow-Joe is just an idiot.
I for some masochistic reason went to a talk by Joe in the late 70s, during his first Senate term, and before his surgeries, the car crash, and, of course, 30+ years of aging.
I don’t remember anything he said, except that his topic was nuclear proliferation (in which he was supposed to be an expert), and that he was boring as hell. Definitely not the laff-riot he is today.
