His policies and speeches bring definite reminders of nationalistic policies past, of using immigrants as refugees and scapegoats for everything wrong in a society, as well as appealing to traditionalist values, the "things were much better in the old days" rose-tinted glasses mentality.
It is a symptom of being stuck in the past, a wish to bring society back to the imagined "good old days", which never actually existed in the first place.
