Mental problems... What exact mental problems do you think Trump has? He may have some narcissistic traits, but so does pretty much anyone running for President. One thing I know he doesn't have is the penchant to hide, only to answer questions if there is a helicopter nearby, and stay away from the press except on special occasions and after months of preparation. He's already held more cabinet meetings than Biden did during year 4 of his term. Of course these cabinet meetings were public displays of Trump worship... but he's held them.
While meandering his speech does not give me the idea that he's lost or incapable, he purposefully does what he calls "the Weave" and meanders. I notice that your Attorneys General who filed charges against him never once had an inkling he might not be able to aid in his own defense, for instance.
I do not see the same things I did with the Autopen, I saw signs of dementia and pointed them out from during the campaign all the way to now, he has not gotten better.
That doesn't mean I won't watch for them, or that I think he's "awesome", it just means I don't think we have a case that he has dementia.
