I have always believed that, too.
The job of POTUS is beneath him. And it is actually a “job”, which he has never had prior to now. I think he is finding out that it kinda sucks.
He ran, won, made history - time to move on. He can go be Sec. General of the UN, be “citizen of the world”, soak in global adoration, not have to work.
As Jesse Jackson once said, “He’s never run anything but his mouth.”.................
