He's always delivered word salads, but now appears to be more confused. He exhibits strange posturing/coordination with that weird fist pump thing that he tries to do. Ongoing reports of his odor suggests incontinence.
He might be able to whip up MAGA acolytes with angry invective, but he has dementia.
I too would avoid verifying the odor problem. I believe that some concerned Republicans are running the smear campaign about Trump's smearing. To be fair, they don't specify, and he could be incontinent of urine instead of fecal incontinence. He could be incontinent X 2, but that specific sort of information hasn't leaked yet.
