Mmm... just a thought here. In terms of the Senate and House, that's working as appropriate. Rural areas not dominating cities and cities not dominating rural areas. One would need a policy popular in both to create a national policy (otherwise you create a city or state policy instead). It's a good balance between tyranny of the minority and tyranny of the majority.

In terms of the electoral college, perhaps something similar could be done. Not sure how though.
