Making most possible Dem/Rep CD by state or nation with 2016/2020 data

[nclib]

I made an AL district similar to AL-4 with making AL-5/Huntsville a relative Dem sink, and got 87.4% Trump in 2020. If someone could explain how to post a link, I will post it.

Even though PA-3 is the most Dem actual CD, I imagine gerrymandering NYC/Chicago could get one higher.

By state, for NC, Dem would be from Winston-Salem to Raleigh (Charlotte is probably too far and there's Repub areas in between it and W-S), and Rep would be making NC-11 a relative Dem sink, and using the next furthest west areas, while avoiding the Triad.

You could also probably tweak CA-13 (Oakland/Berkeley) to make it even bluer.

Or an extremely blue one in North Georgia that combines both of the lunatic idiots' districts.

By disregarding the VRA and packing black voters you can make 80% black districts in each of Detroit, Chicago, and NYC that would be D+47 under 16/12 numbers and probably D46 by 20/16. Of those, Detroit would be the bluest.

I have not fully gamed out this exercise for Republicans, but the clubhouse leader has got to be a Northern Alabama seat that gets into the high-80s. I don't think you can get redder than that, but if you can it's by taking TX-11 and TX-13 and dropping the "bluer" areas in each to create one massive sprawling red district.
