What Biden's inner circle did should be illegal. They could have made up for their handling it the way they did, by insisting Biden drop out of the Presidential candidacy early on. When Biden was having difficulty handling the duties of the presidency no matter how major or minor they were, the inner circle knew good and well that the difficulties would only become progressively worse. They should have delivered an ultimatum to Biden, that if he didn't drop out of the race, then they would reveal his present difficulties. The inner circle of aides should have banded together at least as early as February or March. They were having to cover for him enough that early on, that they knew the reality.
They need to be instigating legal age limits now. Possibly they may have to wait till someone is in office that is not past the age limit though. It wouldn't look that positive if Biden or Trump were in office and put into effect laws that would invalidate their presidency. This wouldn't take care of the 5-10% of dementia patients that are early onset, but it would take care of at least 90% of the 'future' patients deciding whether to run.
