The liberal has become synonymous with elite. If you disagree with a liberal you're uneducated, angry, racist, or pick any other disparaging word. It has caused a divide that crosses right/left, and is instead top/bottom. According to a poll NPR quoted, ~40% of registered democrats voted for Trump. That is why Hilary lost. The Republicans AND Democrats have become parties of the elite. The rise of Trump and Bernie came from those people who are rejecting elite regardless of party.
