Maybe the Pirate Party can try positioning itself as the anti-EU party and get a new lease on life!
I can't see a bunch of youthful, left leaning protest votes going all Eurosceptic. The Pirate's voters don't strike me as the type who would vote for a UKIP.
They could be. In Scandinavia there is a strong left wing anti-European tradition and Northern Germany is not that culturally different. The EU is committed to fiscally conservatie goals with anti-inflation policies and fiscal austerity deemed more important than fighting unemployment. It is also viewed by many left wingers to be a bureaucratic monster that is pro-big business adnd the establishment. So you dont have to be a conservative to be a euro-sceptic.
