"Big. The Biggest. Tremendous, tremendous, tremendous. Biden. Look, it's very sad. But I really...we're going to..."

16. Our "leader" is batshit crazy. It's not just garden-variety old-age dementia

where they don't remember recent events, get lost, don't recognize people, can't remember words, forget how to operate a toaster, leave their glasses in the refrigerator. That's Alzheimer's. What Trump's got is something else (or maybe dementia on top of it). He's not senile, or merely senile; he's barking mad. I'm not a psychiatrist and I don't even play one on TV, but I've been around older people with age-related dementia and I've never seen or heard that kind of word salad from any of them. My mother, for example, was confused. She forgot where she was, she couldn't remember names or where she had just been. That's not Trump.

He knows where he is and he's fundamentally aware of events, people and places - but he conflates all these things and makes up completely ridiculous stories about them. Either he knows he's making shit up and he's intentionally engaging in weapons-grade gaslighting, or he's decided that these things are all true because he wants them to be true - or both. This isn't Alzheimers; it's lunacy, and it's more dangerous because his aides and family can't (or won't) manage him or hide his madness. If he were just senile he could be taken upstairs for a dish of pudding and a nap; he wouldn't have the capacity to blast out crazy shit on fake Twitter - but he's nuts and he's being enabled by bad people.
