Personally I think using gerrymandering to explain the bulk of our political dysfunction is mistaken. If you were to ask me to give you a simple explanation for the dysfunction and corruption at the federal level, it would be that our federal government is not design to be this big and powerful. Just one example... 50~ years ago the federal government contributed nearly nothing to local and state funding. Today, total federal outlays have ballooned to nearly 20% of all local/state funding(depending on how its counted). Everything has trended to be more centralized.

I believe the best solution going forward is to rip power from the federal government and return it to states and local governments, as was intended by the constitution. Resolving gerrymandering and campaign finance laws will not fix the political dysfunction. It's structural. Most federal institutions are not designed to be democratic.
