Part of his power is that he has an extraordinarily mobile face. Some people find his repertoire of smirks, shrugs, scowls, smiles, and clownish mugging (as in the photo) irresistible.

They love his cha-cha moves with lowered brows, and they love when he lowers his brows and smiles broadly while pointing at random suckers in the crowd to establish the cheap illusion of personal interest. They love how he applauds them applauding him.

Add to these his large size, idiosyncratic long tie, newly golden hair, super-modulated voice, frequent insults, scorn for logical argument, and mastery of verbal conning techniques, and you have a juggernaut of demogoguery, dear to millions.
