What actually happens is he can speak clearly and confidently on issues for half an hour or an hour straight in front of cameras, and he makes one or two stumbles, and Fox etc never show the normal part, but jerk off about the errors endlessly. Listening to Biden talk shows no evidence he has dementia. The claims like “he doesn’t even know what room he’s in!!” are just stupid, and it’s fairly insane considering the former republican president is one of the stupidest, most insanely rambling people ever to hold public office.
