There are countless reasons ( none of them very good) why about 35% of any nation's populous is always quit eager to follow a Trump or Hitler type personality.

These moronic leaders usually depend on giving hatred and self-loathing a target upon which they and their may project. Hitler once said that if Jews didn't exist he would have had to invent them. Indeed hatred is the most powerful of unifying agents, it being the negative side of the trible impulse of a crude intellect.
