I am a dual EU citizen (which countries is irrelevant here, but both full EU members) and am wondering which of my two countries I should register to vote in for the next European Parliament Elections, in order to maximize the "value" of my vote.
Based on this answer I can only vote in a single country, but from this answer by the EU Commission:
the Commission considers that the possibility for EU voters with a dual nationality to choose where to vote should be encouraged.
My question comes from the observation that one person's vote doesn't exactly count as one in a variety of elections.
I assume variables to consider probably include ratio of elected parliament members to population (as the EU Parliament seats are allocated according to degressive proportionality), but there are probably other elements to take into account.
How should I approach this question, and what information should I take into account?
