I mean, the US President basically lives on a Golf Course when he is not on vacation, signing EOs in the white house in his free time.

And we don't see any signs of PD with him, like repeating the same words over and over in a constant slur of nonsense, lecturing journalists about MS-13 Tattoos that are clearly not photo-shopped and totally do exist and clearly his overall sense of reality is impeccable, as his AI generated Gaza Strip promo video and a picture of him as being the Pope proves.

I don't see any validity in this study at all. FAKE NEWS.
