From Daily Kos Elections, the breakdown of how Presidential voting went in each of Texas’ 36 Congressional districts:
Two districts did in fact flip on the presidential level: Trump lost the 24th District in the Dallas-Fort Worth suburbs while recapturing the 23rd District along the border with Mexico. Biden, however, made major gains in a number of other suburban districts and nearly won no fewer than seven of them. Trump, meanwhile, surged in many heavily Latino areas and likewise came close to capturing three, but except for the 24th, every Trump seat is in GOP hands and every Biden seat is represented by Democrats. The 24th, which includes the suburbs north of Dallas and Fort Worth, is a good place to start because it saw one of the largest shifts between 2016 and 2020. The district began the decade as heavily Republican turf—it backed Mitt Romney 60-38—but Trump carried it by a substantially smaller 51-44 margin four years later.
Biden continued the trend and racked up a 52-46 win this time, but the area remained just red enough downballot to allow Republican Beth Van Duyne to manage a 49-47 victory in an expensive open-seat race against Democrat Candace Valenzuela.
Biden fell just short of winning seven other historically red suburban seats: the 2nd, 3rd, 6th, 10th, 21st, 22nd, and 31st, where Trump’s margins ranged from just one to three points and where the swings from 2016 ranged from seven points in the 22nd all the way to 13 points in the 3rd, the biggest shift in the state. However, as in the 24th, Biden’s surge did not come with sufficient coattails, as Republicans ran well ahead of Trump in all of these seats. (You can check out our guide for more information about each district.)
Two seats that Democrats flipped in 2018 and stayed blue last year also saw large improvements for Biden. The 7th District in west Houston, parts of which were once represented by none other than George H.W. Bush from 1967 to 1971, had swung from 60-39 Romney to 48-47 Clinton, and Biden carried it 54-45 in 2020. Democratic Rep. Lizzie Fletcher won by a smaller 51-47 spread against Wesley Hunt, who was one of the House GOP’s best fundraisers. The 32nd District in the Dallas area, likewise, had gone from 57-41 Romney to 49-47 Clinton. This time, Biden took it 54-44 as Democratic Rep. Colin Allred prevailed 52-46.
Biden’s major gains in the suburbs, though, came at the same time that Trump made serious inroads in predominantly Latino areas on or near the southern border with Mexico. That rightward shift may have cost Team Blue the chance to flip the open 23rd District, which stretches from San Antonio west to the outskirts of the El Paso area.
A full breakdown by county and district is here, and a comparison of percentages from 2016 and 2020 is here. CD23 went from being a Romney district to a Clinton district to a Trump district, though in all cases it was close. The red flags are in CDs 15, 28, and 34. In CD15, incumbent Vicente Gonzalez won by only three points, in a district Biden carried by one point, a huge drop from Clinton’s 57-40 win in 2016. Everyone’s least favorite Democrat Henry Cuellar had an easy 19-point win, but Biden only carried CD28 by four points, down from Clinton’s 20-point margin. It’s not crazy to think that Jessica Cisneros could have lost that race, though of course we’ll never know. This wasn’t the scenario I had in mind when I griped that CD28 was not a “safe” district, but it does clearly illustrate what I meant. And Filemon Vela, now a DNC Vice Chair, also had a relatively easy 55-42 win, but in a district Biden carried 52-48 after Clinton had carried it 59-38. Not great, Bob.
We don’t have the full downballot results – we’ll probably get them in March from the Texas Legislative Council – but the Harris County experience suggests there will be some variance, and that other Dems may do a little better in those districts. How much of this was Trump-specific and how much is long-term is of course the big question. The Georgia Senate runoffs, coupled with the 2018 results, suggest that having Trump on the ballot was better for Republicans than not having him on the ballot. On the other hand, 2022 will be a Democratic midterm year, and the last couple of them did not go well. On the other other hand, Trump is leaving office in complete disgrace and with approval levels now in the low 30s thanks to the armed insurrection at the Capitol, and for all the damage he did to the economy and the COVID mitigation effort, Biden is in a position to make big progress in short order. It’s just too early to say what any of this means, but suffice it to say that both Ds and Rs have challenges and opportunities ahead of them.
There are some very early third-party efforts at drawing new Congressional districts – see here and here for a couple I’ve come across. We still need the actual Census numbers, and as I’ve said before, the Republicans will have to make decisions about how much risk they want to expose themselves to. The way these maps are drawn suggests to me that “pack” rather than “crack” could be the strategy, but again this is all very early. There is also the possibility that the Democratic Congress can push through voting rights reform that includes how redistricting can be done, though the clock and potentially the Supreme Court will be factors. And if there’s one thing we should have learned over the last 20 years, it’s that due to Texas’ rapid growth, the districts you draw at the beginning of the decade may look quite a bit different by the end of the decade. We’re at the very start of a ten-year journey. A lot is going to happen, and the farther out we get the harder it is to see the possibilities.
