People are just fed up. They're fed up with elites telling them what to do. Then they elect strongmen (Trump, Erdogan, Putin, Duterte, Chavez, Maduro etc). 

These guys aren't really conservative or liberal in the traditional sense. They all want power, and they all want to push their agenda through. Maduro/Chavez for instance are leftists. Trump is more of rightist, as is Erdogan. At the end of the day, people voted for a dictator because that's what they want. They see that whether conservative or liberal, they all drift toward the center and the center hasn't been very good to them.
