There was no cover-up and there was nothing wrong with President Biden

[Ocelot II]

30. What was "wrong" with him was that he was 81 and showed it,

and whether he could have handled another term as president is a fair question. However, there doesn't seem to be significant evidence that he was unable to do his job at any point in his first term, or that someone else was making decisions or handling the work. The illnesses and weaknesses of presidents and other leaders have been kept out of the public eye since forever, and to a much greater degree than this. After Wilson had a stroke in 1919 his wife Edith was effectively the president, and his illness really was covered up. The public didn't know FDR almost always used a wheelchair. Hardly anybody knew JFK had Addison's disease, and Reagan's gradual decline into Alzheimers was downplayed or ignored. Biden was never a very good speaker, and his age made his voice weaker and his stutter harder to suppress, which made him seem more frail than he really is. What the public saw of Biden - his speeches and interviews - showcased his weakest attribute, but his day-to-day work of managing the executive branch was not seen, although the results were. And there's no evidence at all that he was weak or failing in those respects, or that anybody else was doing that work.
