Pro tip: almost all the attention tonight will be on #NJGov, #VAgov and NYC mayor, but for '26 clues I'll be watching what happens in VA's House of Delegates. Here's why... Nationally, the median House district voted for Trump by 3.1 pts in 2024. Depending on the final outcome of redistricting, Dems will need to hold/flip seats that voted for Trump by 3-5 pts to win control.

NEW: as expected, TX Republicans unveil a 30R-8D gerrymander (up from 25R-13D today) that puts Reps. Henry Cuellar (D) and Vicente Gonzalez (D) in double-digit Trump districts and axes one Dem seat each in DFW, Houston & Austin/San Antonio. Image Interestingly, however, the map doesn't *totally* doom Cuellar & Gonzalez. Cuellar's #TX28 would move from Trump +7 to +10, Gonzalez's #TX34 would move from Trump +5 to +10. Both are potentially survivable given ancestral Dem ties & a midterm without Trump on the ballot.

Thread: the key difference between when Biden was “counted out” last time vs. now is that in Feb. 2020, there was a plausible path to a comeback: Black voters & other Dems of color in SC, etc. hadn’t weighed in yet. In fact, I made the argument after IA/NH in 2020 that there was still a lot of upside for Biden, though that view wasn’t widely shared at the time, and that he was among the most electable Dems in the race vs. Trump. nbcnews.com/news/amp/ncna1…

How is it Dems are cleaning up in special elections/referendums if their national poll numbers are so bad? Because in the Trump era, Dems are excelling w/ the most civic-minded, highly-engaged voters.

Their biggest weakness? Peripheral voters who only show up in presidentials. A big reason Dems beat pundit/historical expectations in the midterms? Only 112M people voted, including a disproportionate turnout among voters angry at Dobbs/abortion bans (many of them young/female).

But there will be ~160M voters in 2024. So who are those extra 48M voters?

On the other hand, Trump-endorsed Charles Herbster (R) is on track to lose the #NEGOV GOP primary badly. Herbster doing a little better with more Trump-aligned EDay votes reporting, but still not on track to win. #NEGOV

Fact: of the 301 new House districts that have now been adopted, just 17 (5.6%) went for Biden or Trump by five points or less, down from 39 of 301 (13.0%) districts in the same states currently. Back in 2012, after the last redistricting round, 66/435 districts went for Obama or McCain by five points or less. By 2020, only 51/435 districts went for Biden or Trump by five points or less - in other words, voter self-sorting explains a lot of the competitive decline.

NEW: for the first time, Dems have taken the lead on @CookPolitical's 2022 redistricting scorecard. After favorable developments in NY, AL, PA et. al., they're on track to net 2-3 seats from new maps vs. old ones.* *There's still quite a bit of uncertainty in:

- FL, where Rs are debating how aggressive to be
- NC/OH, where courts may order big changes to GOP maps
- PA, where the state Sup Ct will select a map
- AL/LA/SC, where SCOTUS could decide on additional Black opportunity seats

NEW: Dem leaders in Albany are set to release maps in the next 72 hours, but there's still tension between Marc Elias/Sean Patrick Maloney - who are pushing for a hyper-aggressive 23D-3R gerrymander - and Upstate Dem incumbents who'd like more minor changes to their districts. At issue: it's theoretically possible to draw a 23D-3R gerrymander w/ 23 double-digit Biden seats (example, left). But it would require Dem Reps. Paul Tonko #NY20, Joe Morelle #NY25 and Brian Higgins #NY26 to give up some existing blue turf (current map, right).

BREAKING: national Dems are using a "communities of interest" argument to urge their Albany counterparts to adopt an aggressive 23D-3R gerrymander that could wipe out five of NY's eight GOP seats. nyirc.gov/storage/commen… Image Highlights of the 23D-3R plan recommended by commenter "Sean Patrick:"

- Staten Island #NY11 drawn in w/ Lower Manhattan
- New maj-min #NY02 on Long Island
- #NY27 Jacobs (R) merged w/ #NY23 Reed (R)
- #NY22 Tenney (R) put in a D-leaning seat
- #NY03 crosses Long Island Sound

Thread: yes, the new House map is on track to be slightly more *equitable* (less pro-GOP) than the current one. But keep in mind, it's also on track to feature:

- Even fewer competitive seats
- Even wider disparities in maps' treatment of non-white voters from state to state I think @mcpli's broader point is fair, but the way I'd frame it is that vastly different standards are being applied to non-white communities in TX vs. IL, AL vs. VA, etc. depending on partisan motive, absent a clearer set of VRA rules from SCOTUS/Congress.

NEW @CookPolitical: Republicans are still clear favorites in 2022, but there are poised to be perhaps 3-8 *more* Biden-won seats after redistricting than there are now - creating a House map less biased towards the GOP than the past decade's. cookpolitical.com/analysis/house… So far, district lines are complete (or awaiting sign-off) in 293 districts, more than two thirds of the House. There are 15 seats that have shifted from GOP-leaning to Dem-leaning @CookPolitical PVIs, and just 9 that have moved the other way.

Thread: which party is "ahead" in redistricting? In my view, it's close to a wash. But the truth is, it depends which metric you use.

As @Nate_Cohn has alluded, tracking by district partisanship (slight Dem gain) differs from tracking by seat control (neutral/slight GOP gain). New Jersey's new map is a perfect illustration. By @CookPolitical PVI (a measure of districts' 16/20 prez performance vs. national result), three seats have gone from R-leaning to D-leaning: #NJ03, #NJ05 and #NJ11.

Meanwhile, one seat moves from D-leaning to R-leaning: #NJ07.

BREAKING: here’s the new NJ congressional map that throws #NJ07 Rep. Tom Malinowski (D) under the bus and shores up Reps. Andy Kim (D) #NJ03, Josh Gottheimer (D) #NJ05 and Millie Sherrill (D) #NJ11 for a likely 9D-3R split. *Mikie, not Millie (damn autocorrect)

NEW: California's near-final draft map looks terrific for Dems. All 42 Dem incumbents (except retiring Rep. Alan Lowenthal (D), whose Long Beach seat is folded in w/ LA Rep. Lucille Roybal-Allard (D)'s), get strong seats.

Meanwhile, *five* of 11 GOP seats get more vulnerable. Biggest winners on this draft map:

#CA07 Bera (D) - Biden +14 to +18
#CA10 Harder (D) - Biden +3 to +11
#CA39 Kim (R) - Biden +10 to +2
#CA45 Porter (D) - Biden +11 (unchanged)
#CA50 Issa (R) - Trump +8 to +12

New: Virginia special masters' map eliminates Abigail Spanberger's (D) current suburban Richmond #VA07 & turns it into a safe Dem seat in Northern Virginia. Rep. Elaine Luria's #VA02 would remain highly competitive, for a 6D-4R-1C split overall. By the numbers, this might be a slightly better map for Dems than the current one (5D-4R-2C), but much better for Republicans than had Democrats retained redistricting power and drawn an 8D-3R gerrymander.

NEW: the first official draft map from California's commission is here, and it's both a major shakeup and a mixed bag for the parties. Early read: it could perform quite well for Rs in 2022, but offer longer-term upside for Dems. Read on... wedrawthelinesca.org/draft_maps ImageImage First, the five biggest "losers" in this draft (which will change before 12/27):

#CA10 Harder (D) - Biden +3 to Trump +10
#CA22 Nunes (R) - Trump +5 to Biden +9
#CA40 Roybal-Allard (D) - seat eliminated
#CA48 Steel (R) - Biden +2 to +9
#CA50 Issa (R) - Trump +8 to Biden +1

NEW: FL's Senate Rs release four draft congressional maps. Bizarre: these maps shore up #FL27 Rep. Maria Salazar (R), but otherwise are barely gerrymanders. By my count these maps break down 16-12 Trump-Biden, vs. 15-12 today. Is this a head fake? These maps would put #FL15 Rep. Scott Franklin (R) in the new safe R #FL28, but turn #FL15 into a *Biden* seat in the east Tampa suburbs - effectively creating a new Dem seat. I can't imagine this is going to be the ultimate GOP plan in FL.

Deleted an earlier tweet because the figures cited by the registrar below did not include 2k+ mail ballots. At this rate, Charlottesville would be on pace for ~15k votes, still down from 16.5k in 2017 and potentially a weak turnout in an 86% Biden city. There are still 9 hours for this to change, but the main turnout concern for Dems today isn't white college grads in Northern Virginia, it's young/non-white voters who were super-motivated in the Trump era but not so much today. #VAGOV

First read: this "starting point" map for the CA commission is decent for Rs. It eliminates a Dem seat in LA County (as expected) and imperils Harder (D) in #CA10, while leaving all incumbent 11 Rs w/ a path to victory (though Nunes & esp. Issa would face much tougher races). Notable shifts in this early "visualization" (North):

#CA01 LaMalfa (R) - Trump +15 to +6
#CA04 McClintock (R) - Trump +10 to +8
#CA07 Bera (D) - Biden +14 to +4
#CA10 Harder (D) - Biden +3 to Trump +1
#CA21 Valadao (R) - Biden +11 to +9
#CA22 Nunes (R) - Trump +5 to Biden +3

Breaking: as predicted, IL Dems have revised their proposal to a safer, more aggressive 14D-3R gerrymander. It's still about as ugly as before, though. google.com/maps/d/viewer?… ImageImage As I hinted last Sunday, this version creates a new, much-anticipated Latino seat (#IL03) on the north side of Chicago. But, it would do so by merging the homes of Reps. Marie Newman (D) and Sean Casten (D) in a reconfigured #IL06.

VIRGINIA: Dems hold a 7D-4R lead on the current map (below). But in 2020, Dems/voters approved a bipartisan commission that's proven dysfunctional thus far, likely punting redistricting to the right-leaning VA Supreme Court. Here's why that's a big deal... If Dems had kept power (or even if commission were to draw a compact map, example below), they could have easily shored up #VA02 Rep. Elaine Luria (D) w/ Norfolk & #VA07 Rep. Abigail Spanberger (D) w/ Charlottesville, and maybe even made #VA01 Rep. Rob Wittman (R) vulnerable.
