I think it was already 20 years ago when a French sociologist whose name I have forgotten showed that the share of vote for the Front National clearly correlated with various negative economic variables, including "distance from the closest still functional railway station".
FYI I don't believe in "THE REASON" or "THE CAUSE" and I am wary of people who reduce complex issues such as voting patterns to one single root cause, but to deny that economic hardship is a significant factor in anti-system vote seems to be wishful thinking to me.
Show me a relatively rich neighbourhood or voting district (say, over 130 per cent of average national GDP) with above average anti-system vote share, anywhere in Europe. I don't think you will find it. People who have a lot to lose don't rock the boat.
