Let me call this the Trump Effect. Jacques Attali nails it:
It is, first of all, a vote by a clear majority who believe the future can be better than the past. As in the United States and Great Britain, the main political debate is precisely this: is going back to the past better than going forward? We have answered differently than others in the Brexit and Donald Trump votes. France has sided decisively with the future. Emmanuel Macron has defined that forward path as liberal progressivism.
Brexit was a close vote. Trump was a close electoral vote. France’s vote was a landslide against nationalism. Wait until 2018.
