“He’s stinky” is a schoolyard taunt if it’s not true, or if it was a one off issue and it never went away. If this adult can’t take care of his own hygiene, that reveals some deeper issue that’s probably worth discussing. Couple that with noone likes working with someone who stinks, so it calls into question his effectiveness as a leader.

But more importantly, his cult followers view him as some strong alpha male. If they see the reality that everyone who gets close to him is laughing at this man-child behind his back, were less likely to end up with him as president and that’s a good thing.
