A hallmark of the Trump presidency is its fear-based approach to governing. Dangerous Muslim terrorists; corrupt, colluding fake news media; caravans of violent migrants coming to eat our children and curse our livestock, or something -- evidently, Trump has no qualms with fomenting fear to advance his agenda. (To debate another time: does he have an agenda?) As harmful as this Trump presidency may be, his strategy leans upon tried and true methods of political manipulation. One such example: McCarthyism.
