If you aren’t comfortable with labeling this as dementia, that’s fine. But there is no question that the president — the man tasked with making critical life and death decisions for both the country and the world — is struggling with mathematical concepts, has vivid “memories” that are not rooted in reality and has an increasingly foggy grasp of past events that did happen. That’s not a medical diagnosis. These are facts we can see for ourselves and we all know, even those of us who voted for Trump three times, that this can’t be allowed to continue.
