Instead of talking about the Constitution I suggest we talk about age
If you remember, before Biden decided to step down many here commented that, hey, they are over 70 and would not trust themselves to perform the duties of a president.
No one really can tell when the systems start slowing down. Remember, we did have a president while suffering the early stages of Alzheimers. (And is still revered).
There are many cultures where the elders are revered and rule societies but not us. We have always been the young, energetic country that continues to re invent itself. We have led with invention and development in science and technology, in art and entertainment. Sure, he still performs but his act is getting stale. When I see him sitting at his desk while Musk stands above him I am thinking that he realizes his weaknesses and therefore got Musk to carry his ideas.
I share the same year as all three: Trump, Bush and Clinton (though younger) and it is time for us, the oldest boomers to clear the stage for the next generation.
This, I suggest, should be our approach.
