again: i agree with this, but trump seems a little less senile, over all.
if i were to put odds down, i'd say there's a 75% chance that biden gets dementia in the next four years and a 100% chance that he gets it in the next eight, if he survives that long, whereas i'd say there's a 49% chance that trump doesn't get through the next four years.
