Gerrymandering backfires when voters change parties easily and frequently. Loosely held party loyalties keep politicians on their feet and forces them to focus on actual voter's issues. When voters dogmatically lock-in to a party affiliation for decades/generations it leaves politicians with zero incentive to listen to them and shifts their focus to drawing safe-districts. The best way for voters to be heard is to radically reject all party-lock-in-narratives and fire anyone who is in a safe seat - irrespective of everything else.
