As a rule of thumb, I'd say 1/6 of the vote going to xenophobic parties should be considered 'normal' in Europe. It's when they start polling above 20% and becoming the second largest party (or the first!) as in the Swiss SVP or Wilders in the Netherlands that one can talk about something anomalous going on.

Often this vote will be hidden in mainstream right-wing parties and the explicitly senophobic options remain marginal (as in Spain) but it doesn't mean that 1/6 of the voters aren't xenophobes.
