However, for the same reason I don't think a parliamentary system would work, I don't think this would work, either. We need to keep it similar enough to the US to hold interest on the US Election Atlas forum.
I like nothing more than a functional parliamentary system. I don't think that keeping this game modeled on the U.S., just because it's the "U.S. Election Atlas" is a right approach. We need to have an ability to develop our unique identity, instead of following one template.
However (I believe it was Oakvale that pointed this out one day on IRC), we're not big enough to adopt a functional parliamentarism, that is we're not large enough to be able to crave out working parliamentary constituencies.
