As I explained two weeks ago (in comments), Le Pen had no chance of winning in an electoral system that holds an anarchic free-for-all primary election, and then just two weeks later a general election.
There was not enough time to heal wounds and build a coalition between the Le Pen and the cuckservative factions. I'm guessing a lot of the low turnout this time was due to these comfortable retired cucks, who cannot settle into a fundamentally new mindset (nationalism) after just two weeks of attempted persuasion.
These are the people who would have cost Trump the election if it had been held two weeks after Super Tuesday of primary season. He needed months to get them on board. That Le Pen was able to get 40% after two weeks of coalition building is pretty good -- does anyone think Trump would have done better if the election had been held in early April, around the time of the disastrous Wisconsin primary?
An earlier post from a year ago detailed the superiority of the American system of holding primaries far in advance of the general, which results in the two-party system instead of the free-for-all system that the Europeans have. Not only does it allow plenty of time for healing and coalition-building after a bitterly fought primary, it also allows the winning party to hit the ground running after the election. They do not have to waste months in putting together a coalition after already taking office, since that coalition was formed before the general election was even held.
Between a sorely needed overhaul of their electoral process, shameless de-Gaul-ification by the EU, rampant third-world immigration, and Islamic terrorism, France is headed toward another one of its bloody revolutions. Europe and its off-shoots is due for its once-a-century major war, and their rhythmic tendency is to occur during the first half of the century.
The Pentagon brass would absolutely support the violent imposition of Islam and mass migration on all European peoples, if those peoples went to war to try to expel the foreigners. Hopefully our rank-and-file troops would see the absurdity of pointing guns at Englishmen and Frenchmen in order to grease the skids for Islamic mass migration, and would either half-ass it or actively disobey.
This further delay in solving the immigration problem will only increase the pressure-cooker atmosphere in Europe, and raises rather than lowers the probability that Europeans will ultimately turn toward pogroms or a Reconquista against their invaders, if the democratic process offers them no peaceful civic remedy. It is in the nature of laissez-faire zeitgeists for short-term buck-passing to take the place of long-term stewardship, but eventually everybody has to pay the piper.
