Front National is going to gift the PS victory here just like Marine Lepen and the centrist guy gifted the presidential victory to Hollande. Lepen says that the FN is neither leftist or rightist but her actions have made her the most far left person in France.
The FN is a nationalist socialist party, so it doesn’t fall into the traditional left/ right cleavage like we have in America.
Marine Le Pen is a statist, and IMO has much more in common with the Socialist/communist Left than with the tradition right in France that is traditional, free market, definitely capitalist, and supports individual initiative and smaller government.
MLP’s tacit support of the Socialist Hollande was a grudge match vengeance against Sarko and his party. Her goal is to destroy UMP and become THE party on the right in France. She will, and has allied with the devil to destroy her perceived opposition.
As the French say “on verra” we’ll see.
