California would be really intersting to see how agressive Dems go.
Colorado would also be interesting to see if Dems keep Colorado Springs whole. A 6-2 map is very possible by giving CO-03 more of Boulder County, but 7-1 is pretty difficult because of geography
In Colorado the main question is if they would be brave enough to split Denver- that's the one thing that would make aggressive gerrymanders possible as you wouldn't be sinking so many Democratic voters then.
If they were as aggressive as Illinois was, then a 6D-2C-0R map like this (with Hispanic-majority 1st, as a Hispanic district would be the obvious excuse for making a Denver split) could be on the cards.
