Yeah, I should've guessed...are there any large cities where they did (relatively) well?
That depends on your definition of well. The SGP does well in the bible belt, but mainly in the villages and towns. Their highest share of the vote (51%) was in Urk which has a population of 20.000 people.
Here are the results of the largest cities (these are cities with 150.000 people or more)
Rotterdam 0.9%
The Hague 0.5%
Utrecht 0.3%
Eindhoven 0.2%
Almere 0.3%
Groningen 0.4%
Tilburg 0.1%
Breda 0.1%
Amersfoort 1.1%
Enschede 0.4%
Nijmegen 0.1%
Haarlem 0.2%
Thanks for the info. I already knew where they did best (Urk, Staphorst and other such great places); and I'm not surprised to see they don't perform so strongly in the larger cities. God bless the Dutch Bible Belt!
