I've always preferred a larger legislature but have concerns over a body comprised of all the citizens. A body double the size of the Senate wouldn't be such a terrible idea in my opinion. It would also give us some interesting new legislative opportunities, such as the creation of committees, which is unfeasible in our current legislature due to it's size, while still retaining the excitement of running for and holding the elections.
I don't think that we currently have enough persons in Atlasia to have a second elected house of government, even with dual office holding. If we had a much larger population in Atlasia, I could support both houses being elected.
