"Impartial Automatic Redistricting... optimized for equal population and compactness only."
IMHO, more important than eliminating Gerrymandering, is eliminating the two party system. In truly competitive governments with 10-15 parties holding seats, it's incredibly risky to lie, BS, or ignore arguments. In our two party system most of the arguments are just designed to talk you out of voting at all if you favor the other party.

The US only has a two-party system because our method of voting ensures that it devolves into a two-party system. Our two-party system is a symptom of the problem, not the cause.
Give us ranked voting and proportional representation and we'll see more than two parties emerge.
For example, Richmond and Sausalito should not be in the same district, and the Sacramento river should be a divide at least as far up as Antioch and Rio Vista.
Likewise, Vashon Island in WA should not be split across 2 congressional districts, but (since too small to be a district on its own) should be entirely in one of the districts it has a ferry connection to. And Puget Sound should be a hard divide.
The politicians would never allow it.
