Then why did so many vote extremist anti EU? There just has been EU election in germany and the nationalist gained a lot. And none of the big parties otherwise said a clear no to that, so what could I do, except vote a small party against that, but too small to really do something?
Voters care. But they see often no point in voting anymore.
Here in France, the "extremists" got a bit over 30% of votes. But turnout was only 51%.
According to [0] average turnout is 51%. Some countries have very high numbers (IIRC voting is mandatory in Belgium?), others ridiculously low. This, to me, means pretty much that "voters don't care".
This is simplistic. Some have simply lost confidence in their representatives and/or cannot find a decent candidate.
