Nobody wants to talk about it, but given that we talked about it endlessly with Biden, we should be talking about it with Trump as well: he's getting older. He's never been a particularly intellectually curious or, frankly, mentally stable person, but the base case is to assume that all of these traits are going to be enhanced as he ages and as he begins to slow down mentally (which, people avoid it, but is very likely happening).
It reminds me a lot of my late grandmother.... it literally took her driving the wrong way down a four-lane divided highway until she got the keys taken away and ended up in assisted living. Trump is the POTUS version of this right now.... and absent the GOP finding their balls (I will be calling my rep's DC office and yelling today), I don't see him losing the keys anytime soon.
