@CaliZaybak No, he doesn't know how to communicate naturally! Witness his exaggerated laughter for a case that did not deserve it!
He seems to be enormously insecure and tries to compensate by overdoing reactions to other speakers!
Where Trump is obviously immature, a 10 year-old trying to act as an adult, De Santis is totally ill at ease among ordinary people! He lacks the charisma needed to compete with the kid from New York!
