Just curious, but how likely is it a newly unified Democratic govt somewhere out there tries to change the maps before 2020?
I looked up Illinois and New Mexico, and
http://redistricting.lls.edu says both of them appear to allow Congressional redraws but not legislative. These are both states where Democrats would have an incentive to shore up certain districts
(or in IL's case, try to soften others up as well).Not sure if any of them have ever tried doing this within the past few decades, but Illinois is the easiest to picture trying if it is in fact possible.
