The racially gerrymandered “black” districts are a mess and produce the worst Representatives in Congress. Sheila Jackson-Lee (flag on Mars), Hank Johnson (Guam capsizing), Maxine Waters (Socialize your companies) etc, etc.
The problem is that if you unpacked these districts, you would jeopardize Conservative Republicans in adjacent seats by dumping these moonbat, brainwashed and racist Communist voters into their districts (and tip them to the Dems). Look at FL for example where the legislature was forced to “fairly” help more Dems to office by increasing the number of moonbat voters. Giving the GOP a free hand to pack the nutters into a few seats gives the GOP more districts and makes them safer (instead, it handed roughly 5 House seats to the Dems).
