The reason I bring this up is because people were expecting (or hoping) that the populist would end up winning the election -- and he lost. So could this theoretically happen in France with Marine Le Pen? Bear in mind both countries are totally different. I believe the dutch are less open to populism right now and the French are.
France has suffered through a historic amount of terrorism from radicals and thus Marine Le Pen is most likely more favourable. Additionally, she has been leading all French polls and, with a month left before the election, she's still got an extraordinary lead.
After analyzing the Netherlands' situation, I knew the populist wouldn't win simply because they weren't ready. But you cannot be too naive towards people who are mad.
The US was mad. Super mad for their failed policies on both sides of the spectrum. They voted Trump.
France is super mad because their values have been lost. They will vote Le Pen.
