I forget who asked me over Thanksgiving, but someone was puzzled by the rise of the far right, especially Nazi-types in places that experienced the Nazis.
Well, for Greece, the answer is obvious:
What more do you need to know? In really harsh economic times, people turn to blaming others and supporting politicians who do so. People were surprised by the rise of xenophobia in Finland, for instance, but this figure would make that seem a bit less puzzling. An interesting study for a comparativist would be to see where the far right did less well during these difficult times and perhaps where the far right is doing better than they should (UK, Germany).
Of course, this is just about the state of the national economy--it does not speak to inequality within these economies nor to anything else. Still, pretty damned instructive.
