The two greatest problems I see with the position of the ThirtyThousand.org cited by JEQuidam:
* at some point, a legislative body that is far greater in number than the present is likely to be far less productive (perhaps thats a good thing to some), far more argumentative and devisive, and with no guarantee (or even likelihood) that it would be more responsive to "the people".
* The larger the number of representatives, the greater the disparity between states - large v small, sunbelt v rustbelt, etc.
IMO, as I stated earlier, a better solution is a greater use of technology to connect legislators with the people.
For more on Madison (and
Federalists 55-58), I would encourage folks to read the original.
And, I too, welcome JEQuidam to TFP politics!
