Another potential obstacle is between parties that have governed and those that have only shouted from the cheap seats.To Law and Justice or Fidesz, which, despite a populist bent, have run their countries for years, leaders like Le Pen, who never has, can still appear toxic.

But “she is still seen as an eternal outcast, somebody who never played a government role,” said Pawel Zerka, of the European Council on Foreign Relations.
