I'm not a doctor and if I was, I would not likely give a diagnosis on Biden's mental state on the internet. My grandfather lived with my mom while he had Alzheimer's until it was unmanageable. My mother lived with me for a time when she had Alzheimer's until we couldn't manage it. My non-authoritative opinion, based upon my experience with the tragedy of loved ones who are no longer cognitively competent is that Biden is unfit to be POTUS at this time.

25 years ago, he was Mr. Law & Order and too conservative to be in today's Democratic Party. We all change with age, I have, but my concerns about him are not just a matter of political view. We are in times too dangerous for him to be POTUS. My opinion of course.
