JOE BIDEN: Hide the (Cognitive) Decline. “One or two senior moments on the campaign trail wouldn’t have hurt him (mainly because of the (D) after his name). But it’s not one or two a campaign, it’s one or two an appearance, it’s mistakes segueing into non-sequiturs segueing into a buffet of word salads.”

He also seems to be getting shorter-tempered and meaner, which in my experience — admittedly amateur — are both signs of dementia.
