This is two years old article - as far as I know the German pirates now are rather leftist (actually too leftist for my liking - but as a whole the pirate movement is rather balanced between the two poles).

Pirate Party as a new and mostly undefined movement attracted all kinds of freaks - but it can only work as a movement of those that understand how the Internet can be used in politics, both the dangers and the potential for good, and who value the freedom and openness that was associated with the early net.
