Sure .. but 'less' so.

In the EU, European Union, member countries are voting on EU positions .. whether it's weighted or unweighted, it's a collection of N countries voting, not a collection of N millions of people voting.

Similarly in the USofA, formed as a union of states to have a common government for those things that are agreed to superseded individual state interests.

I live in a country with mandatory voting - everybody (of age, save for those convicted of _serious_ crime) votes, and ranked proportional voting.

Compulsory voting offends the sensibilities of a number of USofA citizens, but there is a strong case to be made for it, ranked voting does a lot to avoid two party Hotelling's law quagmires where major parties barely represent anybody and yet MySportingTeam divisions dominate.
