Methinks it also has to do with the nature of the campaigns: content-free, and almost only national in focus, making the elections pointless.

(If I'll find the time, I'll put together a diary on some campaign slogans in Hungary).

Even at the one place where the EP elections seem to count something, in Bavaria, it's for local reasons: the Bavarian CSU is struggling to pass the 5% limit valid across all of federal Germany on its own. So the CSU is making a lot of noise, while various public interest groups try to push the CSU in its tight situation.
