The interesting thing is that the places where they got a lot of votes hardly have any immigrants at all - it's a splendid example of being afraid of the unknown and how that fear is used by extremists.
This makes me wonder if "voting" is actually any good, is it really "democratic"? Maybe if a vote was actually an informed choice, but most people just go with whomever is the most popular or promises them the moon on a stick. Realism, reason, legality, etc does not matter. Perhaps "voting" is not democratic at all if the people are basically ignorant, shortsighted, easily swayed by (the illusion of) popularity, fearful, during times of uncertainty and with many doubts about the future; We already see a kind of political aristocracy in most western democracies, the sons of presidents becoming presidents. Maybe that a demarchy would have been a better idea?
