Agreed. Also, as well as your prudent reforms I'd suggest a flat rule to be implemented across the country requiring congressional constituencies to be required to comply to a single standard around density and shape to prevent or at least minimise the current gerrymandering both parties practice. No more of these farcical ones that are 25 blocks long and one block wide to avoid a clump of enemy voters!
Absolutely. I believe someone has proposed expanding the US House such that each Rep represents 500,000(?) people. I forget what the name of the plan is, but it has some good points. And I agree with you about the oddly shaped districts created by gerrymandering.
