US House Redistricting: Iowa

[lfromnj]

As the Iowa GOP has expanded their majorities in both chambers there is a good chance they could ignore the commission .







They can either go for a 4-0 map or a 3-1 map if they chose too. The GOP could probably sweep a 4-0 map in a Biden midterm although 3-1 just make everyone happier and 4-0 would probably go badly just like a pure 3-0 in NM could go a bit badly.

numbers in those?

Trump +15 each for first and Trump +6 is the closest in the  2nd map.

Put together a State Senate map:

Seat composition:
2016: 34 Trump — 16 Clinton
2018: 31 Reynolds — 19 Hubbell

State House map:

Seat composition:
2016: 66 Trump — 34 Clinton
2018: 57 Reynolds — 43 Hubbell

Can you get these maps color-coded for partisan purposes?  I have no doubt I will see a Republican sea of red (or Atlas blue) interspersed with a few tiny Democratic islands, but still.  

Are these meant to be Republican gerrymanders, or is it just the nature of geography in Iowa that Dems will win a much lower % of the seats than their PV performance reflects? Specifically looking at the share of Hubbell seats relative to his ~48% share of the popular vote.

The latter. The current map is fairly similar in the number of Clinton districts.

So is it possible to make a State Senate map and a State House map where the median seat voted for Reynolds by the same margin as the state as whole and Hubbell won a percentage of seats equal to his statewide vote share? Bonus points if county splits are kept to the minimum necessary.
Also: does the geography get better for Ds or worse when the districts get bigger?

better clearly as the median district goes to like 5 points left of the state.
