Hi!
I was thinking about this today. Why did the Nordic countries turn out Social democratic countries and liberal?
Is there something particular in their history that would explain this?
There was a thread like this several seventeen days ago with a particularly good answer from /u/vonadler on the part of social democrats in Sweden and a briefer answer from another user on the part of Finland's social democrats.
EDIT: Corrected some things.
This might also be a good question for /r/AskSocialScience.
