Trump's inability to write is NOT a sign of dementia. It's a sign of something worse.

11. I think most of those things

are simple indications that he's really not all that bright, never really learned to read or write -- certainly never learned certain basics of spelling -- and is generally quite ignorant of most things.

I also have my doubts that he actually has a diagnosible dementia. Of course, I could be entirely wrong about that since I don't know a whole lot about dementia, other than there are a number of different kinds and that generally a person with any kind of dementia goes downhill in a more or less straight line.

Of course, dementia or not, he is supported, cosseted, and protected by those around him. Although why they would continue to work for him simply boggles the mind.
