Why do they have to fit into one chamber? And, IMO, fruitful debate has not been a feature of Congress during my lifetime. Logistically, each party would choose its leadership, and the House as a whole would choose a Speaker. They would handle the nuts and bolts of when and what legislation would come up for a vote. It would be interesting to have a lot more granularity in representation -- you'd certainly have reps from the Greens and the Libertarians, along with any number of other parties that were suddenly viable.
