Gerrymandering has been practiced by both members of the duopoly for decades. Every ten years the state legislature majority party picks its voters by adjusting district boundaries to its advantage. Since there is no mention of political parties in the Constitution, the Supreme Court does not intervene in the state's right to establish district boundaries unless they constitute racial discrimination - not partisan discrimination. As long as there are single member districts there will be strong incentives for gerrymandering. The solution for fair representation is large, multi-member districts.
