2022 #Midterms Simulation: #ArtoftheGerrymander

A Republican House win will be built on gerrymanders (TX/GA/FL/TN/LA, etc.)

To illustrate the need for fair maps, I'm calculating the results using the 2022 votes, but if every state had a Democratic gerrymander. #ElectionTwitter ImageImageImageImage

I’ll apply the difference in Presidential margin to the House result. Thanks @davesredist @mikemathieu @vest_team + @DKElections @PoliticsWolf

Keen to see how my maps perform over the decade; tried to comply with state law if partisan intent were allowed to stand.

This pulls back from the red rural counties of the fajita strip, and picks up more of Hidalgo - keeping the Rio Grande Valley blue. (@RepGonzalez may have stayed). ImageImageImageImage
Real #TX21: R+13 PVI, Rep Chip Roy +25.8%
My TX-21: D+6 PVI, @PoderConClaudia +10.8%
Population overlap: 30%
Takes far more of Austin and its suburbs. Losing counties like Hays and Hill was too much for Roy to overcome. ImageImageImageImage
Real #TX23: R+5 PVI, Rep Tony Gonzales +17.2%
My TX-23: D+9 PVI, @LiraForCongress +11.6%
Population overlap: 25%
This shifts further into San Antonio, giving up the border counties. Gonzales would likely have shifted to the 27th, which has more of his exurban San Antonio base. ImageImageImageImage
Real #TX38: R+12 PVI, Rep-elect Wesley Hunt +28.1%
My TX-38: D+6 PVI, Duncan Klussmann +6.2%
Population overlap: 25%
Swaps some Houston suburbs to become plurality Hispanic. This bluer seat overlaps, but a majority of @Lizzie4Congress constituents are in the blue-trending #TX07. ImageImageImageImage
#ArtoftheGerrymander: #Arkansas
Trump 62.4% - Biden 34.8%
Real delegation: 4R
Gerrymandered: 3R-1D
Δ Share of D seats: 0% => 25%
Votes aren't certified yet, but this map appears to have narrowly worked.

Real #AR02: R+9 PVI, Rep French Hill +24.9%
My AR-02: D+4 PVI, @DrQHathaway +0.2%
Population overlap: 63%
Little Rock and Pine Bluff combined with the Delta makes this a black-opportunity district. Though it's the whiter suburbs of Little Rock, Conway, and Bryant driving it left. ImageImageImageImage
#ArtoftheGerrymander: #Colorado
Biden 55.4% - Trump 41.9%
Real delegation: 5D-3R
Gerrymandered: 7D-1R
Δ Share of D seats: 63% => 87%
This makes #CO08 more firmly Hispanic-plurality (43%), giving @YadiraCaraveo more breathing room; while flipping 2 seats.
davesredistricting.org/join/135d8a6c-… ImageImageImage
Real #CO03: R+7 PVI, Rep Lauren Boebert +0.2%
My CO-03: D+3 PVI, @AdamForColorado +19.4%
Population overlap: 52%
With the real race conceded, we can see Boebert's extreme underperformance (much like MTG in GA-14). Boulder and Grand Junction are both moving the district left. ImageImageImageImage
Real #CO05: R+9 PVI, Rep Doug Lamborn +15.8%
My CO-05: D+1 PVI, @Cd5Torres +1.8%
Population overlap: 38%
Pueblo is a strong base of votes; but it's not trending left like Colorado Springs & the ski resorts. Lamborn may well have jumped to the 4th with the rest of El Paso County. ImageImageImageImage
#ArtoftheGerrymander: #Florida
Trump 51.2% - Biden 47.9%
Real delegation: 20R-8D
Gerrymandered: 19R-9D
Δ Share of D seats: 29% => 32%
Republicans won 3 of the 6 seats decided by <5%; flipping a seat to partly offset the 2 they lost (even holding #FL27).
davesredistricting.org/join/5b43b96d-… ImageImageImage
Real #FL03: R+9 PVI, Rep Kat Cammack +26.2%
My FL-05: D+7 PVI, @HawkforCongress +6.5%
Population overlap: 50%
Rep @AlLawsonJr likely runs in this 29% black-opportunity district. It combines his Tallahassee base with Gainesville. (Allows Jacksonville district to become 38% black). ImageImageImageImage
Real #FL13: R+6 PVI, Rep-elect Anna Paulina Luna +8.0%
My FL-13: Even PVI, @EricLynnFL +2.4%
Population overlap: 75%
One of the few Democratic overperformances in Florida - perhaps thanks to @CharlieCrist's home-base support in Saint Petersburg. ImageImageImageImage
Real #FL22: D+7 PVI, Rep @LoisFrankel +10.2%
My FL-21: D+2 PVI, Dan Franzese +0.1%
Population overlap: 74%
The first R-flip. I split Democrats in Palm Beach County too much, in an attempt to get a black-opportunity seat out of the 18th (parts of Port Saint Lucie to Delray Beach). ImageImageImageImage
#ArtoftheGerrymander: #NewJersey
Biden 57.3% - Trump 41.4%
Real delegation: 9D-3R
Gerrymandered: 11D-1R
Δ Share of D seats: 75% => 92%
Tried to unseat Gottheimer in #NJ05 primary (24% Asian + 20% Hispanic). #NJ10 still plurality-black. #NJ12 now 32% Asian.
davesredistricting.org/join/1c4f788f-… ImageImageImage
Real #NJ02: R+5 PVI, Rep Jeff Van Drew +19.0%
My NJ-02: D+5 PVI, @talexander_NJ02 +0.7%
Population overlap: 54%
Cuts out Vineland and white working class towns in Ocean and Atlantic counties, allowing Atlantic City to be combined with Camden and other Philly suburbs. ImageImageImageImage
Real #NJ07: R+1 PVI, Rep-elect Tom Kean Jr. +3.0%
My NJ-07: D+7 PVI, Rep @Malinowski +12.2%
Population overlap: 47%
This is still based in the Central Jersey suburbs, but swaps out rural and exurban Republicans for much bluer suburbs. ImageImageImageImage
#ArtoftheGerrymander: #Washington
Biden 58.0% - Trump 38.8%
Real delegation: 8D-2R
Gerrymandered: 8D-2R
Δ Share of D seats: No change
Same overall result, but much more cushion in #WA03 & #WA08 + #WA05 was a toss-up. Also made #WA09 36% Asian-opportunity.

#ArtoftheGerrymander: #NewYork
Biden 60.9% - Trump 37.8%
Real delegation: 15D-11R
Gerrymandered: 19D-7R
Δ Share of D seats: 58% => 73%
Managed to salvage 4 seats, except surprisingly #NY24 (Zeldin + Tenney's incumbency was enough). #NY25 was a close call.
davesredistricting.org/join/b561989c-… ImageImageImage
Real #NY01: R+3 PVI, Rep-elect Nick LaLota +11.8%
My NY-01: D+5 PVI, @bridgetmfleming +2.5%
Population overlap: 35%
Kept the northern coast of Long Island, but swaps the Hamptons and other eastern parts to pick up suburbs on either side of Long Island Sound. ImageImageImageImage
Real #NY17: D+3 PVI, Rep-elect Mike Lawler +0.8%
My NY-17: D+5 PVI, Rep @spmaloney +2.1%
Population overlap: 44%
Still based in Rockland County; but replaced lighter blue suburbs east of the Hudson River with deep blue Yonkers. But Sean Patrick Maloney's home is in my 19th. ImageImageImageImage
Real #NY19: Even PVI, Rep-elect Marc Molinaro +2.2%
My NY-19: D+4 PVI, Rep @JoshuaUE99 +7.0%
Population overlap: 27%
This is still based in the Hudson Valley, but picked up some blue cities in the lower Hudson Valley, instead of Ithaca and other parts of the Southern Tier. ImageImageImageImage
Real #NY22: D+1 PVI, Rep-elect Brandon Williams +1.0%
My NY-22: D+4 PVI, @FDConole +5.5%
Population overlap: 48%
Still based in the Syracuse suburbs, but picks up Ithaca and Binghamton, while losing urban Syracuse and red, rural parts of Central New York. ImageImageImageImage
#ArtoftheGerrymander: #California
Biden 63.5% - Trump 34.3%
Real delegation: 40D-12R
Gerrymandered: 41D-11R
Δ Share of D seats: 77% => 79%
Some D Hispanic underperformance: Rs won 7 of the 12 decided by <5%. (Also made #CA13 &#CA37 more black-opportunity).

Real #CA01: R+12 PVI, Rep Doug LaMalfa +24.0%
My CA-05: D+7 PVI, @MaxSteinerCA +4.9%

Combines Chico with wine country (particularly Santa Rota), while cutting out Yuba City and most of the Shasta Cascades. ImageImageImageImage
Real #CA03: R+4 PVI, Rep-elect Kevin Kiley +7.2%
My CA-01: D+2 PVI, @DrKermitJones +4.5%
Population overlap: 46%
Still based in North Sierra Nevada around Lake Tahoe; but picks a dense tendril of Sacramento suburbs in place of the redder Placer County exurbs. ImageImageImageImage
Real #CA13: D+4 PVI, Rep-elect John Duarte +0.4%
My CA-16: D+5 PVI, @AdamGrayCA +2.1%
Population overlap: 61%
Fairly similar, with Modesto, Turlock, and Merced. But shifts north to pick more of Tracy and Livermore, losing Madera and Los Banos. Just enough to flip the seat for Ds. ImageImageImageImage
Real #CA21: D+9 PVI, Rep @RepJimCosta +8.0%
My CA-22: D+3 PVI, Michael Maher +2.8%
Population overlap: 63%
Shifted the district south, losing the northern suburbs of Fresno, and picking up Visalia, Tulare, ad Porterville - which was enough for this district to backfire. ImageImageImageImage
Real #CA33: D+13 PVI, Rep @aguilarpete +15.4%
My CA-31: D+3 PVI, John Porter +0.7%
Population overlap: 31%
Overstretched the district's Hispanic voters in the San Bernadino suburbs, by losing the urban core and picking up Redlands, Moreno Val, and Temecula. ImageImageImageImage
Real #CA38: D+14 PVI, Rep @LindaTSanchez +16.2%
My CA-39: D+5 PVI, Eric Ching +0.9%
Population overlap: 23%
Shifted this east, making this a more Asian-opportunity district than Hispanic, 37% Hispanic-35% Asian district. Also made it just competitive enough to flip to Rs. ImageImageImageImage
Real #CA39: D+12 PVI, Rep @MarkTakano +15.4%
My CA-41: D+2 PVI, Aja Smith +3.0%
Population overlap: 64%
Combines Riverside with South Menifee and Murrieta, giving up the Morena Valley and Jurupa Valley. But yet another Hispanic underperformance cost a Dem seat. ImageImageImageImage
Real #CA41: R+3 PVI, Rep Ken Calvert +4.6%
My CA-35: D+4 PVI, @WillRollinsCA +7.8%
Population overlap: 45%
This Corona and Lake Elsinore based district swaps out Menifee, Palm Desert, and Palm Springs, and instead picks up Fontana, Ontario, and Jurupa Valley. ImageImageImageImage
Real #CA48: R+9 PVI, Rep Darrell Issa +20.8%
My CA-42: D+2 PVI, @electhoulahan +0.5%
Population overlap: 32%
This still has the city of Escondido; but picks up Vista, San Marcos, and Imperial county, giving up Murrieta, Temecula, and southern San Diego County. ImageImageImageImage
Real national: 222R-213D
Gerrymandered: 266D-169R
Δ Share of D seats: 49% => 61%
Shows how district lines can change the results, even if not a single votes changes. @RepDonBeyer’s #FairRepAct would provide #FairMaps. #ElectionTwitter

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

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.

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

@JMilesColeman @mikemathieu @PoliticsWolf @DKElections @Redistrict
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
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
