I would rather have a more limited lower house. Maybe all elected officials from the regions (and limit it to 5 max so that no region gains an advantage). That way those positions are worth more, will be more competitive, but you do have a pretty large lower house.
Elected officials, federal and regional? Or just regional?
I feel that cabinet members should be either in the Senate or Lower House and they should be responsible to both chambers.
I disagree. I believe Cabinet members should only have their one duty to the Cabinet. I think that we should expand the positions of the Cabinet to make them more uselful in this simulation.
