@emacsen The EU also kinda has an electoral council. Voters in small states have a larger weight in the EU parliament & EU Council.
This has a certain logic. Representatives of certain countries are quite likely to vote together, rather than on ideological lines. If given equal weight, it is not attractive for a small country to join a union. Even with current rules there was a period in which the votes of Luxembourg could not have changed a decision.
No longer valid for US.
There are so many differences between the US and the EU.
There is no "President of the EU" due to the difference in structure. The US president even holds more power than most prime ministers, and US citizens vote for that office directly ever since 1824.
