Since I spent the time pulling it together, thought I'd share a rough projection of #Redistricting2021 with #ElectionTwitter (notwithstanding some uncertainty). 1/34

This uses the Census Bureau's December apportionment estimates. bleedingheartland.com/2020/12/23/iow… @DrRyanPhd
Getting the 1-seat states out of the way: 2/34
• AK-DE-ND-RI-SD-VT-WY: 4R-3D

Moving on to GOP controlled states:
• ID & WV are uniformly red: 2 R each
• No reason to expect any changes in MS: 3R-1D
• Or AL: 6R-1D
• AR: 4R (they can probably make the 2nd uncompetitive)
FL: 17R-12D 3/34

State redistricting laws + 2 new seats makes me imagine they’ll leave existing D seats alone, & add a new one in South FL. Then they can safely add an R seat around Orlando (& maybe try to flip another given 2020 Latino movement), while shoring up FL-26 & 27.
GA: 9R-5D 4/34

Republicans are likely to pack the 6th and 7th into one new safe D seat. But I’m a little more skeptical they’ll carve up the AA-influenced 2nd (to avoid legal risks).
IN: 8R-1D 5/34

They’ll definitely reinforce the 5th by packing Dem suburbs into the 7th. Obama’s performance in IN likely spooked them in 2011, but can’t see why they won’t try to crack IN-01 now.
MO: 6R-2D 6/34

GOP is definitely cracking the insecure MO-02. But they didn’t crack the AA-influenced MO-05 last time, I presume because of legal risks. However, MO got redder so they could push further.
NE: 3R 7/34

Rs will shore up NE-02, but it’ll still be competitive, both because they like the attention paid to state priorities from making it a semi-competitive Presidential battleground, and because of trends – it swung more toward Ds than any other Electoral College votes.
NH: 1R-1D 8/34

Given their poor performance under 2 competitive seats (1 out of 10 this decade aka NH-01 2014), easy to imagine they’d go for a surefire safe seat.
NC: 9R-5D 9/34

NC GOP seem sure to try & claim NC’s new seat, while leaving the existing court-mandated 5 D-seats However, I like the odds of the Dem state SCOTUS – even reduced to 4D-3R – intervening to produce a fair 8R-6D map.
OH: 13R-2D 10/34

Can’t see why GOP won't capitalize on favorable geography+trends. It'll be challenged in court.

They might protect OH-13 to try to keep Ryan from running statewide. Otherwise, Dems best hope is suburban trends dummymandering a few seats.
OK: 5R 11/34

Oklahoma City is probably getting carved up.

SC: 6R-1D

Don’t know how, but GOP will certainly do something to crack SC-01. Though trends could still make it interesting by the end of the decade.
TN: 8R-1D 12/34

Republicans left TN-05 alone out of fear of 2010’s rural Democrats bouncing back. Hard to see the same qualms next year.

TX: 26R-13D

Huge blow for Dems not to win the state House. This seems quite likely.
UT: 4R 13/34

With McAdams losing, Republicans could easily shore up the existing gerrymander.

Dem's best shot is for the commission to recommend a compact map (with Salt Lake City seat) that GOP tweaks to their preferences.
And now Dem controlled: 14/34

No reason to expect big changes; just tweaks to shore up incumbents:
• CT: 5D
• MA: 9D

IL: 14D-3R

They've learnt their lesson (dummymandered IL-12 & 13 based on Obama's performance), plus have suburban gains to shore up.
MD: 8D-1R 15/34

They didn’t draw a 9D last time. However, the Dem supermajority can override Hogan, & Republican's ruthlessness (e.g. WI, NC, OH) might prompt them to go for it this time.
NM: 3D 16/34

Hard to imagine that Dems won’t try to get XTS back in NM-02, now that they have control this time round.

Though I imagine demographics will push for 2 Hispanic & 1 high-Native American district.
NV: 3D-1R 17/34

They can shore up their vulnerable incumbents by packing rural NV-02.

OR: 5D-1R

It’ll be shocking malpractice if Dems don’t try for 5 seats.
NY: 21D-4R 18/34

With Dems finally in full control (sans IDC), I expect they'll push to counterbalance R-gerrymanders. I drew a 23D-3R map (before NY losy a 2nd seat). So they *should* be able to go for at least 21 (without stretching the 1st or 4th).
And finally split control / independent commissions: 19/34

AZ (Commission): 6D-4R

Seems realistic (with probably 4 competitive seats, just like there were 3 toss-ups in 2012 – the AZ redistricting commission has to maximize competitiveness).
HI (Commission): 2D 20/34

IA (Commission): 3R-1D

Axle seems in good position with Des Moines trending blue.

CO (Commission): maybe 5D-3R

Given trends, but 2 of those will be marginal.
KS: 3R-1D 21/34

GOP will probably compromise with Kelly by packing KS-03, to prevent a dummymander (by spreading blue suburbs across 2nd & 3rd).

LA: 4R-2D

Similarly, JBE probably gets a 2nd Dem district.
KY: 5R-1D 22/34

With Beshear in office, Republicans may settle for incumbent protection. Though if Republicans kept everyone on board, they could override a Beshear veto for a 6R seat.
MI (Commission): 7D-6R 23/34

New criteria require partisan fairness, so should be better for Dems than current R-gerrymander, but likely 4~ competitive seats given crosscurrent trends.
MN: 4D-3R 24/34

If GOP Senate & Walz don’t agree on an incumbent protection map, easy to see a court combing MN-07 & 8, which are losing pop, while keeping the 2nd a Dem-incumbent toss-up.
ME: 2D 25/34

Assuming Golden keeps hold of ME-02. It's possible Mills leaves it to courts, if that seems more likely to improve ME-02 than GOP legislature.

MT (Commission): 2R

Though the Western 1st will be competitive in waves
NJ (Commission): 10D-2R 26/34

The commissioner went with the R's gerrymander in 2011, which backfired on them. With suburban trends, Democrats are even more efficiently distributed Ds, so hard to imagine their incumbents will be in a markedly worse/better position than now.
PA: 9D-9R 27/34

Unless they agree on incumbent-protection; I’d bank on a deadlock between Wolf & the R-legislature, with the PA SCOTUS drawing another fair map. Wouldn’t be surprised if Dems & Rs swapped PA-08 & PA-01 in 2022
WI: 5R-3D 28/34

Even if Evers & the legislature gridlock, GOP control the state SCOTUS, & geography is very R-favorable. That being said, I can see the 1st and/or 3rd being made more favorable for Democrats, but both still a challenge (sans Kind's incumbency).
WA (Commission): 7D-3R 29/34

Easy to see the existing map consolidated. WA-06 & WA-08 will be the ones to watch. (WA-03's geography helps Herrera Beutler).

VA (Commission): 7D-4R

With 2 South VA AA distrcts, likely that 2nd & 7th stay competitive.
CA (Commission): 45D-7R 30/34

While a commission; Dems have been good at appealing to the criteria, which emphasize communities of interest, & lack a partisan fairness criteria. So they may well be able to target the 4 Biden-Republican districts in CA. cookpolitical.com/analysis/natio…
This breaks out to 225D-210R, but this likely lowballs Rs for 2022 – both because there is more downside risk for Dems in above estimates (e.g. FL, MO, AZ, NJ, CA), & relies on some vulnerable incumbents in R-leaning seats (e.g. IL, ME, PA, NJ, VA). 31/34
This #Redistricting2021 projection shows the #ArtoftheGerrymander problem from another angle. 33/34 #ElectionTwitter

Commissions beat partisan control, but need partisan fairness criteria (mandating “efficiency gap” metrics by drawers). @PoliticsWolf dailykos.com/stories/2017/5…
But even well-designed commission (with partisan fairness requirements) can't deal with changes within given lines over a decade. 34/34

Only multi-member districts can truly fix it. @RepDonBeyer’s #FairRepAct ensures approximate proportionality. @fairvote
This is probably a better example for GA:
Sorry, I said 8D-1R, when I should have said 7D-1R.

But here is another example of an 8D-0R map:
Dave shows a potential 4R KS gerrymander

But I think the 3R-1D is more likely, both for dummymander/incumbent protection concerns, but also KS GOP's moderate wing may withhold the numbers for a veto override.
Another version of the 7D-4R VA map
I seem to have underestimated how much Dems can be packed into existing South FL. Dave shows how Rs could get both new seats for 18R-11D map. I find it less likely that they'll risk legal jeopardy by pushing further than that.
I miscounted FL and MD (tired). So more like 223D-212R. So things mostly balance out (albeit with unfair gerrymanders on both sides). Median seat likely will still lean-R.

Dem majority will be highly susceptible to a 2022 R-wave (midterm penalty). centerforpolitics.org/crystalball/ar…

Welcome to the #ArtOfTheGerrymander! 1/43

A Dem-map a day to explore:
* state political geography &
* unfairness of single-winner districts
@davesredist +2020 projections #ElectionTwitter

dailykos.com/stories/2019/1…
2/43 Our running total starts: 5D-8R (skipping AK, DE, ND, SD, RI, VT, WY, HI, ID, WV).

NB: I try to maintain communities of interest & relatively compact maps; but compromise for D-maximization (may not comply with local rules). And I apply VRA as >50% primary (not total) pop.
3/43 #ArtOfTheGerrymander: #Utah

First off are some red states with competitive suburban seats e.g. Salt Lake City. I'd rate UT-04 as competitive by default, but would lean D with @RepBenMcAdams' incumbency. #ElectionTwitter

My contribution to keeping quarantined #ElectionTwitter sane: A Tour of the 50 States*

*Equal-population simulation (approximated by counties) 1/40
@JMilesColeman @SenhorRaposa @HarryEnten @Redistrict @ecaliberseven @PoliticsWolf @uselectionatlas @DKElections @Center4Politics
I used Redraw the States to resize them all to 10-11 Electoral Votes (sans DC/3 & Los Angeles county/16).

Electoral College:
2016: Clinton 297-241
2012: Obama 317-221

Then got curious how they voted for Gov/Sen... 2/40
kevinhayeswilson.com/redraw/?share=…
NB: Methodology: I combined results by year-sets e.g. 2012-16 (Sen), and 2013-16 (Gov).

I used the wonderful ourcampaigns.com to pull county results going back to 1957 (i.e. stopped when Hawaii and Alaska were admitted as states + data quality issues that far back). 3/40

Tested it out with this new KY map. Based on 2016-2019 results, intrigued how it would do in 2020. The #KY04 (R+7 PVI) seems more competitive than the real #KY06 (R+9), with the movement in the Cincinnati and Lexington suburbs. 2/27 davesredistricting.org/join/d389d8e2-…
However, I also did a bunch of Democratic gerrymanders after 2012 redistricting to compare with the real Republican ones. Thought I’d review how my designs performed in light of 2016. The contrast shows just how much of a difference partisan control makes (spoiler: a lot). 3/27
