In Paris, it was a Front National festival.As the country woke up in shock, the first French politician to offer The Donald felicitations on his upset victory was a smiling Marine Le Pen, congratulating herself on having called it right again after Brexit.

Then came her closest aide, Florian Philippot, and her niece Marion Maréchal-Le Pen. The next domino to fall, they implied, would be France in next year’s presidential elections.

While the expression worn by François Hollande – the face of a dozen funeral commemorations – seemed to be more of a comment on his own coming defeat, his foreign secretary Jean-Marc Ayrault broke diplomatic protocol to imply defiance: “Mr Trump’s victory is cause for much worry.”

European politics has become unpredictable, an uncharted territory where the only fixed point is the anger of masses of popular voters. They feel the elites have abandoned them to unemployment and the consequences of mass immigration.
