State House district changes by demography

One more look at how state house districts have changed over the decade. For this exercise, I’m going to look at some key counties and the State Rep districts within them.

Bexar:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
122   -1,304  10,628  12,204  21,091  10,900  31,719  20,819
121   -4,020   6,534   6,059  15,078   2,039  21,612  19,573
116     -583   6,014   3,546  10,281   2,963  16,295  13,332
117    4,532   8,828  14,927  22,921  19,459  31,749  12,290
123   -1,427   5,225   3,742   9,272   2,315  14,497  12,182
124      330   5,077   5,877  11,756   6,207  16,833  10,626
125   -1,081   4,378   4,753   9,350   3,672  13,728  10,056
120     -184     863   4,503  10,856   4,319  11,719   7,400
119    1,062   3,428   6,041  10,507   7,103  13,935   6,832
118    1,391   3,719   6,633   7,790   8,024  11,509   3,485

Bexar County doesn’t get the props it deserves for contributing to the Democratic cause. Each of its ten districts became more Democratic in each of the two Presidential cycles. Where Bexar had gone 51.56% to 47.04% in 2012 for Obama, it went 58.20% to 40.05% for Biden. Obama had a net 23K votes in Bexar, while it was +140K votes for Biden. The two districts that shifted the most heavily towards Dems are the two Republican districts (HD117 went Republican in 2014, then flipped back in 2016), with Biden carrying HD121 as Beto had done in 2018, and HD122 coming into focus as a potential long-term pickup (modulo redistricting, of course). Both HDs 121 and 122 were over 60% for Romney, with HD122 at almost 68% for him. Both can and surely will be shored up in the next round of mapmaking, but the long term trends don’t look good for the Republicans holding them both.

Tarrant:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
092   -1,102   3,986   4,166  13,144   3,064  17,130  14,066
094   -3,344   2,238   2,655  10,231    -689  12,469  13,158
096      821   4,468   6,527  15,522   7,348  19,990  12,642
098     -489   6,891   8,798  13,948   8,309  20,839  12,530
097   -3,267   3,654   6,147  11,472   2,880  15,126  12,246
101     -734   3,487   4,523   9,808   3,789  13,295   9,506
093    2,751   5,180   9,984  15,697  12,735  20,877   8,142
091      401   2,489   5,437   8,897   5,838  11,386   5,548
090     -180   2,391   3,170   5,496   2,990   7,887   4,897
095     -613  -2,745   2,727   7,752   2,114   5,007   2,893
099    2,757   3,282   9,686  11,208  12,443  14,490   2,047

I know everyone sees Tarrant County as a disappointment in 2020. Beto broke through in 2018, we had a bunch of close districts to target, and the Republicans held them all even as Biden also carried Tarrant. The point here is that Democrats made progress in every district, in each cycle (the dip in predominantly Black and heavily Democratic HD95 in 2016 notwithstanding). That includes the strong Republican districts (HDs 91, 98, and 99), the strong D districts (HDs 90, 95, and 101), and the five swing districts. Tarrant will be another challenge for Republicans in redistricting because like in Harris they have mostly lost their deep red reserves. HD98 went from being a 75% Romney district to a 62% Trump district last year. They can spread things out a bit, but remember what happened in Dallas County in the 2010s when they got too aggressive. I’m not saying that’s what will happen in Tarrant, but you can see where the numbers are.

Collin:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
067   -3,022   8,595   6,135  19,411   3,113  28,006  24,893

070    7,648   8,675  21,284  25,686  28,932  34,361   5,429

Denton:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
065   -1,378   6,440   6,048  16,110   4,670  22,550  17,880
106    8,757  11,138  21,190  29,280  29,947  40,418  10,471
064    3,003   6,205   8,257  15,136  11,260  21,341  10,081
063    2,642   6,129  16,382  17,279  19,024  23,408   4,384

I’m grouping these two together because they have a lot in common. Both shifted hugely Democratic over the decade, in each case across all their districts. Both contain a district that was added to their county in the 2011 redistricting. HDs 33 (72-26 for Romney in 2012, 60-38 for Trump in 2020) and 106 (68-31 for Romney in 2012, 54-45 for Trump in 2020) were supposed to be super-red, but didn’t stay that way. I might have thought that the southernmost districts in each county – i.e., the ones closest to Dallas and Tarrant – would be the bluest, but that is not quite the case. HD65 is in southeast Denton, where it is almost entirely adjacent to HD115, but HD63 is the reddest district in Denton (61-37 Trump) and it is the other district on Denton’s south border, though it aligns almost perfectly with HD98, the reddest district in Tarrant. HD64 is the next most Dem district in Denton, and it’s in the northwest quadrant, catty-corner to HD65. I have to assume this is a function of development more than who its closest neighbors are; I’m sure someone who knows Denton better than I can comment on that.

In Collin, HDs 66 and 67 are on the southern end of that county, but so is HD89, where it abuts Rockwall County more than it does Dallas. HD70 is north of 67 and 89, and HD33 (which contains all of Rockwall County) is the outer edge of the county to the west, north, and east, dipping down into Rockwall from there. Both counties continue their massive growth, and I expect them to have at least one more district in them next decade. Republicans have more room to slosh voters around, but as above, the trends are not in their favor.

There are of course other counties that are growing a lot and not in a way that favors Republicans. Here are two more of them.

Williamson:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
136       52  10,901   7,842  22,330   7,894  33,231  25,337
052    2,422   8,335  11,479  22,872  13,901  31,207  17,306
020    7,373   2,895  20,820  14,926  28,193  17,821 -10,372

Fort Bend:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
026   -4,573   9,082   7,327  13,556   2,754  22,638  19,884
028    4,053  14,090  19,260  24,010  23,313  38,100  14,787
027     -461   4,708   6,324  13,724   5,863  18,432  12,569
085    2,908   5,495  10,258  10,161  13,166  15,656   2,490

HD20 also includes Milam and Burnet counties, and I suspect that’s where most of the Republican growth is. HD85 also includes Jackson and Wharton counties. The previous version of HD52 had flipped Dem in 2008, the first such incursion into the formerly all-red suburbs, before flipping back in 2010, but neither it (55-42 for Romney) nor the newcomer HD136 (55-41 Romney) were ever all that red. There were some maps drawn in the 2011 redistricting process (not by Republicans, of course) that carved HD26 out as a heavily Asian swing district (it went 63-36 for Romney as drawn), but it just needed time for the “swing” part to happen. Of the various targets from 2018 and 2020, it’s one that I feel got away, and I wish I understood that better.

Brazoria:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
029      496   8,084  10,828  15,387  11,324  23,471  12,147
025    1,759     215   8,293   3,874  10,052   4,089  -5,963

Galveston:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
024    2,403   3,959  13,045   8,928  15,448  12,887  -2,561
023    3,847     346  11,123   7,296  14,970   7,642  -7,328

Montgomery:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
015   -1,563   7,905  13,226  15,512  11,663  23,417  11,754
016    7,437   2,437  16,088   7,160  23,525   9,597 -13,928
003    7,758   1,807  17,456   8,286  25,214  10,093 -15,121

We’ve looked at these counties before, this is just a more fine-grained approach. Note that HD03 includes all of Waller County, HD25 includes all of Matagorda County, and HD23 includes all of Chambers County. HD23 was already Republican in 2012 when Craig Eiland still held it (Romney carried it 54.6 to 44.2) and while it has gotten more so since then (Trump won it 57.5 to 41.0), that has mostly been fueled by the Republican growth in Chambers. I did a quick calculation on the data from the Galveston County election results page, and Biden carried the Galveston part of HD23 by a slim margin, 29,019 to 28,896. (Republican rep Mayes Middleton won that part of the district 29,497 to 27,632, so this tracks.) The rest of Galveston, the northern part that’s all Houston suburb, is much more Republican, but like with these other two counties one can see a path forward from here. What to do about the likes of Chambers County, that’s another question.

HD29 in Brazoria should have been a target in 2018 but the Dem who won the primary dropped out of the race, and there was no traction that I could see there in 2020. I expect that district to get a little redder, but the same story as elsewhere applies in that the geographic trends are a force that won’t be stopped by boundary lines. As for Montgomery, there are your signs of progress right there. HD15 is still very red, but as I’ve said before, the first goal is to bend the curve, and we’re on the right track there. HD15 is basically the Woodlands and Shenandoah, just north of HD150, while HD03 wraps around it and HD16 is the north end of the county.

Lubbock:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
084     -474     873   4,124   6,975   3,650   7,848   4,198
083    3,359     242  12,224   5,141  15,583   5,383 -10,200

Smith:

Dist  12-16R  12-16D  16-20R  16-20D  12-20R  12-20D Dem net
============================================================
006       67     938   6,922   6,208   6,989   7,146     157
005    4,565  -1,293   9,646   2,832  14,211   1,539 -12,672

These two districts, on opposite ends of the state, may seem odd to be paired together, but they have a couple of things in common. Both contain one district that is entirely within its borders (HD06 in Smith, HD84 in Lubbock) and one district that contains the rest of their population plus several smaller neighboring counties (HD05 also contains Wood and Rains counties, while HD83 contains six other counties). Both have a city that is the bulk of of its population (the city of Lubbock has over 90% of the population of Lubbock County, while a bit less than half of Smith County is in the city of Tyler). And both provide a bit of evidence for my oft-stated thesis that these smaller cities in Texas, which are often in otherwise fairly rural and very Republican areas, provide the same kind of growth opportunity for Democrats that the bigger cities have provided.

Both HDs 06 and 84 were less red than Smith and Lubbock counties overall: Smith County was 69-30 for Trump, HD06 was 68-32 for Matt Schaefer; Lubbock County was 65-33 for Trump, and HD84 was 61-39 for John Frullo. I didn’t go into the precinct details to calculate the Trump/Biden numbers in those districts, but given everything we’ve seen I’d say we could add another point or two into the Dem column for each. HD84 shows a clear Democratic trend while HD06 is more of a mixed bag, but it’s still a slight net positive over the decade and a damn sight better than HD05. HD06 is not close to being competitive while HD84 is on the far outer fringes, but that’s not the main point. It’s the potential for Democratic growth, for which we will need every little contribution we can get, that I want to shout from the rooftops. The big cities and big growing suburbs are our top tier, but we’d be fools to ignore the places like Lubbock and Tyler.
