I’m of the opinion that Biden is benefitting from powerful medications that are tactically administered to increase his lucidity for brief periods of time. Of course such meds have side effects and cannot be used on a persistent basis so his handlers have to decide exactly when he needs them. The meds likely also serve to tamp down the inclination toward angry emotional displays that are so common with dementia.
This all explains Biden’s “lids” and his strictly limited appearances. How long this artificial energy can be effectively applied is anyone’s guess. His handlers must sweat every time he walks out alone.
Note that JoeBama’s Presidential security briefing (which, btw is not normally publicly posted as to time in prior presidents or as to the nature of the briefing— just Pres. Daily Briefing on the scheds.)— occurs at 10:15 in the morning.
10:15 AM? Working Presidents do not have such a light limp schedule, and their days began much earlier. Eisenhower Army discipline, Reagan— full schedule and a worker. Neither Obamuamao or JoeBama (term III of obamaumao) ever worked at much except... bs verbage and imaging appearance vacuous speeches with lots of echo on the sound systems.
