Arkansas is going to be interesting. The gerrymanders may come in the makeup of the primary electorates of each district come 2022. If legislators in the Delta Region want to have a bigger say in Congress, they might just add all of the Delta to just one district, instead of dividing it between the two currently, which does dilute its influence.
AR used to maintain whole counties, but ditched that in the last cycle. Do you see any chance they go back to a whole county plan?
Maybe? It really depends if they want to chop up the 2nd to try and sink Little Rock in a district which is more Republican. And it also depends on how they may want to divide up the state. I'm not sure people would want the 1st to go even further into the Mountains, you could see districts which kinda look like this.
Partisan makeup wouldn't change, but it would make 2 districts based in the more rugged part of the state, and allow for one district which is primarily an agricultural district.
