General Discussion

Like members of SCOTUS, I am capable of talking through hypotheticals. I just not in a state right now where I can entertain the idea that they give us answers.

You're right. It is General Discussion, and indeed, you've discussed. While I appreciate your link to a valid definition of incompetence, I just think that, as far as this discussion relates to this former president, the courts won't go there.
So far, his lawyers haven't even brought up the idea, even if his incompetence seems apparent to millions.

IF they do, and some court finds him incompetent, these years of laying out his "private" v "official" acts will still stand as an historical learning experience for the country, in that it will show the lengths authoritarians will go to use the law and courts to stay in permanent power -- from stealing state secrets, lying, defaming, using government as a business for personal enrichment, purging political rivals from government, to using political violence. It will be an historical lesson to the nation on what secures and endangers Americans' freedom.

Thanks for your thoughts.
