The Arizona Independent Redistricting Commission passed its final maps last night, unanimously. Given that prior cycles had unfortunately ended in partisan accusations, a unanimous vote is a huge success! And, our grades suggest they are good maps too!
First up, AZ's Congressional Map. It gets an A overall and in Partisan Fairness, and Cs in Competitiveness and Geography.

We'd expect it to elect a 5D-4R delegation, though AZ-1, 6 and 8 are all competitive, with AZ-2 and 4 nearly competitive.

It has two Hispanic majority districts (AZ-3 (Southwest Phoenix) and 7 (South Tucson and the southwestern part of the state)). AZ-2 is home to most of the tribal population in the state.
The State Legislative map gets the same grades: A overall and in Partisan Fairness, Cs in Competitiveness and Geography.

It will likely elect a 16R-14D Senate, with five of the seats competitive.

gerrymander.princeton.edu/redistricting-…
It has seven districts with an HVAP over 48%, and one (District 6) with an NVAP over 50%.

We do flag that there is potential backsliding in Hispanic representation - we'd encourage folks who know the population and voting patterns in Arizona to look at this closely!
Again, this is a really tremendous job by the AZIRC. They should be proud of the transparency in their process, the compromises they reached, and the fair and relatively competitive maps they drew.

These maps are now up for public comment, and then the AZ IRC will make final tweaks, but these maps are likely pretty close to the final versions.

The team at the Princeton Gerrymandering Project also has data out for the proposed Alabama Congressional, State Senate, and State House maps.

Congressional: gerrymander.princeton.edu/redistricting-…
Senate: gerrymander.princeton.edu/redistricting-…
House: gerrymander.princeton.edu/redistricting-… Image
For the Congressional map, we fined that it is likely to elect a 6R-1D delegation, the same as the current map.

That one D-district, AL-7, is also a black opportunity-to-elect district, though it far exceeds the 50% BVAP threshold required to make it effective. Image
For the State Senate, we believe it would elect 26R-9D senators.

It has two potentially competitive seats, both near Huntsville.

It has 8 districts with a BVAP over 50%. Image

Another mountain west state that has an advisory commission, Utah's Independent Redistricting Commission also has selected the maps it will propose to the state legislature and we've got grades!
Public SH2 gets an A overall and in Partisan Fairness, and Cs in Competitiveness and Geography. It, along with the other Congressional proposals, would create a Democratic-leaning district around Salt Lake City. Image

Princeton Gerrymandering Project is live with our latest report cards out of Virginia. Maps A7 for the House of Delegates and A5 for the State Senate were released this morning.

A7 House of Delegates: gerrymander.princeton.edu/redistricting-…
A5 State Senate: gerrymander.princeton.edu/redistricting-…
We give the A7 House of Delegates Map a B. It gets a B on Partisan Fairness, a C in Competitiveness, and a B in Geographic Features. It, like several of the maps proposed yesterday and earlier in this process, has a noticeable line of BVAP population above 50%.
We give the A5 Senate Map an F. It gets an F in Partisan Fairness - this map is a Republican gerrymander. It gets a C in Competitiveness and a C in Geographic Features. It also has the noticeable 50%+ BVAP population threshold.

VA SH A6: gerrymander.princeton.edu/redistricting-…
VA SH B6: gerrymander.princeton.edu/redistricting-…
VA SS A4: gerrymander.princeton.edu/redistricting-…
VA SS B4: gerrymander.princeton.edu/redistricting-…
The overall grade for the A6 Draft House of Delegates Map is a B.
The map has slight R advantage, is similarly competitive to other maps that could have been drawn, and contains few county splits.
The overall grade for the B6 Draft House of Delegates Map is an A.
Neither party has an advantage. B6 has average competitiveness, and features compact districts with few county splits.

In view of the midnight deadline for Ohio's Congressional redistricting, the Princeton Gerrymandering Project has a report card for the Draft Democratic Congressional Map.
The overall score is B.
gerrymander.princeton.edu/redistricting-… Image
The map receives a B in Partisan Fairness, meaning a slight D advantage. Out of 15 districts, 8 lean D. Ohio is, roughly, 55R - 45D. The map is barely competitive: only three districts in our competitive zone.
The map retains one Black opportunity district - District 3, formerly represented by Marcia Fudge, currently vacant. This is the same number as the prior map, though the prior map had a Black population of 53.5%. The new district has a BVAP of 41.6%.

We have a report card for the Georgia 2021 Draft Staff Congressional Map. The overall grade is C.
gerrymander.princeton.edu/redistricting-…
The map gets a C in Partisan Fairness - favoring the GOP, with an expected delegation of 9R/5D.
The map gets a C in Competitiveness - despite 0 competitive districts, our findings suggest D and R voters in GA are clustered - there is strong partisan sorting in the state.
Of the districts, there are two which come close to competitive, the 6th & 2nd. The 6th contains Atlanta suburbs, including sections of Fulton and Forsyth Counties. The 2nd, a large southwest district, contains Columbus and Albany.
