Writing in the NYT, Thomas Edison lays out the obvious evidence of a president in mental decline in his opinion piece Trump Has Untethered Himself From Reality.  An excerpt:

 “On April 30 of this year Senators Sheldon Whitehouse and Jack Reed, Democrats of Rhode Island, placed in the Congressional Record a statement by 36 prominent medical specialists questioning Trump’s mental fitness for office: ‘We are compelled to warn of a president of the United States who is increasingly a danger to the public.'”

As further evidence, see his DJYT’s social media post from today, September 15, one day after the Supreme Court ruled against his efforts to suborn the midterms in United States Postal Service v. California et al:

“It is a Court that will go down as having rendered some of the most destructive, hurtful, and damaging decisions in our Country’s history,” he wrote.

Yes, Donald, it will – but not for this ruling. Rather, see Trump v. United States, one giving him almost unlimited immunity for actions as president, and one that will surely go down in infamy as the principal enabler of this corrupt narcissist’s terrible actions.
