I know that there is a list of representatives for my country, and that is comparatively easy to find.
But how do I find the one that is actually there for my sub-sub-sub region? Like: who is the most specific?
Or is it just like this: “Congratulations, here are the representatives of your country. Please do everything else yourself.”
Phrasing it differently: how hard (easy?) is it to participate in democracy, aside from voting?
You don’t have a representative for your region. The EU parliament is based on proportional representation, so seats are assigned based on the share of votes for a given party.
If you want to contact representatives, the list per country is the highest level of detail available. Personally, I’d start with the person or party you voted for.
However there might still be an MEP who is originally from OP’s region and who might be more sympathetic to listen to him. But they arent representing the region.
Probably better to start with the party that aligns with OP’s interests.
