It's called Lewy-Body Dementia.
Related to Parkinson's and Alzheimer's.
And Trump shows most of the symptoms, while Biden doesn't.
The first symptom, the shuffling walk. Trump has that. Look at his ramp walk. Biden doesn't have it. Not a trace.
Second symptom. Sweating, nervousness, dizziness. Again, Trump shows it, none Biden doesn't.
Cognitive problems. Again, Trump affected, Biden not.
Plus, what's with Trump's constant fish lips? That part of his senility is just creepy. As anyone around the senile knows, weird mouth movements are part of the senility.
Based on his rate of cognitive decline, Trump will be wearing a bib and getting spoon-fed by 2022. The good news for Trump is that he won't be competent to stand trial.
