The French left and right come from very different places. The left is urban, cosmopolitan, anticlerical, and anti-capitalist; the right is rural, anti-immigrant, Catholic, and culturally conservative. The two sides have common enemies, however; they hate Macron and the liberals, and they are deeply suspicious of change and powerful foreigners.
It is highly likely that the next French government will try to open the spending taps, which will provoke a strong reaction from both the markets and the more frugal countries in the EU–most notably, the Germans. Then what? Will there be riots in the streets? Will there be an EU constitutional crisis? If the latter, will the French electorate stumble into a Frexit that even the RN didn’t support during the campaign?
All of these are real possibilities, and right before the Olympics. Hang on to your hat.
