I would like to see Iowa in particular, because there is a relatively high chance in Iowa compared to other states that someone could put together what ends up being the real map (or at least extremely close to the real map) using these estimates.
Here's what I made with 2017 estimates:
2012-2016 pvi's:
IA-1(Blue): R+3.28
IA-2(Green): D+4.78
IA-3(Purple): D+2.35
IA-4(Red): R+13.88
Really shows just how empty the western half of the state is without the Des Moines metro. Also shows how "urban packing" can actually work to the Democrat's advantage in Iowa if the same principal is applied here in R gerrymandered states.
Here's the district's populations by 2017 estimates, obviously 1 is overpopulated and 2 is under populated (should be 786,428 per district), but the only real way to correct it would be county splits, which would mess up the estimates.
IA-1
TOTAL 793860
IA-2
TOTAL 776377
IA-3
TOTAL 787147
IA-4
TOTAL 788884

I like this map, but IA-02 would probably violate their rules on compact districts.
