1. Wyoming Rule. No district should be larger than the least populist state.
2. Make DC a Museum. With modern technology there is no need to "send" legislatures to Washington DC, they can vote, meet, etc all remotely. This will make lobbying more expensive, and put the representatives back in their actual communities, because lets face it most of them represent Washington DC not Local Communities.
3. Expand the Term to 4 Years, with a 2 year offset to the president Election. So every 4 years the entire house is elected as a Mid Presidential term Election
