This reminds me of something Adam Griffin did, called the Competitive States of America, a project designed to have as many competitive districts as possible.
Is it possible to have 6 swing districts in South Carolina? (of course ignoring the VRA)
How South Carolina works is basically you have the low state which if it were on its own, would be the most competitive swing state in the southeast. That’s we’re about 4 seats are and you can easily draw these four to be hyper competitive. Then there’s the upstate which were it to be its own state, would likely be the most conservative in the southeast. Potentially America. It’s damn near impossible to get a democratic seat in it. It takes extraordinary gerrymandering (I’ve done it, it’s horrible)
I was thinking that you could uber-pack one district in the northern hills and then draw six districts not safe for either party.
