https://districtr.org/plan/33787https://districtr.org/plan/33881The first has a deviation of 0.38%.
The second has a deviation of 0.47%.
Both have similar enough districts:
FIRST - a western, and heavily Republican, district.
SECOND - a district based in North Iowa that voted for both Obama and Trump, the latter time convincingly.
THIRD - a Des Moines-centric district in Southern Iowa that voted for Obama in 2012 and then somewhat narrowly for Trump.
FOURTH - East Iowa. The Quad cities area, and the only Clinton district.
