I think that's largely down to people not taking EU elections as seriously as national elections.
The ones elected by my country are always largely the most doldrum people from the main parties that aren't charismatic enough to win in national elections (The b-squad basically)
... and a handful of the kind of people that think windfarms generate wind and that we need to leave NATO.. even though we haven't joined NATO. The kind of people you vote to send to the EU so that you don't have to see them.
There was an election in 2024 https://en.wikipedia.org/wiki/2024_European_Parliament_elect...
For people unfamiliar with it https://elections.europa.eu/en/
The parliament is elected by people in each country, those elected them elect the commission. So a form of indirect elections.
No, they don't represent anyone because we, the European people, are voting based on lists, we do not select our own "representatives" by name and surname. This "contact your representative" trope is an American thingie, which, like many American thingies, has no place outside of its original context.
