Trump's family suffered from dementia. Trump shows many signs. The EOs were not written by Trump. He does not know anything about them. The day he took office, there were 150 of them written by various right wing, super wealthy people.lol.
Everyone uses them for speeches, not for press engagements like Biden though...
As I noted, I believe even folks like you watching Trump interact for hours at a time in the Oval Office with the Press while he signed EOs answering questions off the cuff, no 'prompters... even folks like you know that dementia isn't Trump's issue (not saying there isn't one, just saying it isn't dementia).
I also believe that you watched Biden shaking hands with nobody, falling down, shuffling, incapable of finishing sentences, not knowing where he was and wandering off into the forest that one time, capping his day at 9 AM so that he wouldn't have to face questions from anyone, not holding any Cabinet meetings, and when he did they were run by his wife rather than himself, being saved by the Easter Bunny, incapable of following simple directions, tape directions on the floor and notes with YOU ask SO AND SO this, they will talk on this and say that, then YOU will... you watched all of that and ignored it, that crap is on every leftist out there, the press, and every politician that met with him and KNEW...
Your Biden beliefs are reprehensible and wrong. He talked many times during and after the campaign. He spoke as an adult, using an adult vocabulary. He addressed the questions asked, unlike Trump who went off on weird tangents, mostly about his imaginary grievance
Even now, Biden is a lot better communicator than daffy Donald.
He was on The View today answering questions . He spoke directly and openly. You obviously do not value that.
