I am also sad that you really want to destroy the Congressional Black Caucus by eliminating minority majority districts. Your plan eliminated the only districts that these candidates can win in just to elect some "unaffiliated" congresscritters. That is not a trade that I would make
I am sorry that you live in a deep red congressional district. I have also lived in such a district, but I have still fought to change things. In the old days, all of the judges in Harris County were republicans and an asshole named Steve Hotze used to run slates of religious nut jobs for judges. I had a case on appeal from a good republican female judge who was targeted by Hotze (his candidate ran on the platform that females should have no dominion over males). I actually voted in the GOP primary for this judge (who won) and for McCain against W. Luckily that female republican judge was on the bench when my case came back from appeals, and we were able to get a great settlement.
Now, all of the judges in Harris County are democrats and most of the judges in my county are Democrats (sadly the party was not able to recruit and run candidates in all judicial races in 2018). Things can change if you work at it. Democrats should pick up the rest of the judges in my county and strengthen control of the courts of appeal. As for changing voting methods, one of the members of the group of Democratic lawyers that I work with was county election administrator for Harris County in 2020 and he adopted some great innovations to deal with COVID such as 24-hour voting and drive through voting. These innovations were then outlawed by the Texas GOP the next session of the Texas legis. There are things that can be done to make voting easier but it takes hard work to make changes.
Have fun with your silly proposal. This proposal would not work in the real world and luckily no one in the real world would consider this to be a serious proposal. This is the sort of silly plan that people used to run in high school debate where the real world did not matter. Have fun in your world and I will continue to work in the real world.
