It seems that the EU is having trouble figuring out a new voting system. They are apparently having trouble figuring out how to strike a balance between nations and populations.
Look, guys, we figured this out over 200 years ago. I think I can speak for most Americans that you are more than welcome to adapt our consitution for your use. Don’t leave out the bill of rights (*ahem* France).
For this particular issue, let me give you a hint of something that’s worked quite well for us: a bicameral legislature, one house representing the states and the other the population. Just in case you wanted to model your new organization after something that actually works.
