Let me start with some Twitter:

A lot of press has focused on Democratic losses among Hispanics, but important to look at the other side of the coin too (especially given that, uh, Biden won?). But R losses among whites amounted to far more votes, since they are a larger share of the electorate.

Rs managed to find a marginally winning message with Latinos last year. It may have been Trump-specific, maybe not, but “Ds are socialists and we’ll give you jobs” only pushed Trump to 36% of the vote anyhow. They will have to adjust their message for a new generation.

There’s more to the thread, but those are the bits I wanted to highlight. It’s true, as noted in the previous post, that Dems lost some ground in the Latino districts in 2020. You’ll see that here in a minute. But it’s also very much true that they gained a lot of votes elsewhere, in the more white districts. Some of those are the ones that flipped in 2018 or might have flipped in 2020 had they been on the ballot. Some were in places where Dems were already strong. Some were in districts that actually look to be competitive now, having not been so even four years ago. Why don’t I just show you the data?

As discussed before, the columns represent the difference in vote total for the given period and party, so “1216” means 2012 to 2016, “1620” means 2016 to 2020, and “1220” means 2012 to 2020. Each column has a D or an R in it, so “1216R” means the difference between 2016 Donald Trump and 2012 Mitt Romney for the Presidential table, and so forth. In each case, I subtract the earlier year’s total from the later year’s total, so the “-9,951” for SD114 in the “1216R” column means that Donald Trump got 9,951 fewer votes in 2016 in SD14 than Mitt Romney got, and the “56,887” for SD14 in the “1216D” column means that Hillary Clinton got 56,887 more votes than Barack Obama got. “Dem net” at the end just subtracts the “1220R” total from the “1220D” total, which is the total number of votes that Biden netted over Obama. Clear? I hope so.

These are the districts where Dems gained over the course of these three elections. Lots of Republican turf in there, including the two D flips from 2018 and the two districts that both Biden and Beto carried but didn’t flip in 2018 (SDs 08 and 17), but the big gainer is that Democratic stronghold of SD14, where demography plus population growth plus a heavy duty turnout game led to a vast gain. Really, we Dems don’t appreciate Travis County enough. SD15, my district, has a nice showing as well, while SD26 is there to remind us that not all Latino districts went the way of the Valley.

We have the two 2018 flip districts, SDs 16, now practically a D powerhouse, and 10, which didn’t shift quite as much but was the most Dem-leaning Romney district from 2012 – you may recall, Wendy Davis won re-election there despite it going only 45% for Obama – and we have the two Biden-won Republican in 08 – who knew this one would shift so radically left – and 17. We’ve discussed SD07 before, and how it’s now teetering on swing status and won’t be of much use to the Republicans when they try to shore themselves up, but look at SD25, a district that has moved strongly left despite encompassing Comal County, the I-35 version of Montgomery. Look at the shifts in SD12, which is still not competitive but also not as big a GOP stronghold, and SD05, which has moved along with Williamson County. The key takeaway here is that more of the Senate is going to have to be centered on the Houston-San Antonio-D/FW triangle, and that part of the state is much more Democratic than it was a decade ago. This is the big problem Republicans have to solve.

Dems have some room to improve as well. I discussed SD13 in the Harris County reviews, and I believe there’s untapped potential in this district. It’s 80% Democratic to begin with, so improvements in turnout and voter registration are going to pay off in a big way. SD23 was more like 13 in 2016, but acquitted itself nicely in 2020. I suspect there are a lot of voters here who will need more contact and engagement in 2022. I know there were votes left on the table in 2018, and we need to be conscious of that.

Finally, there are three other Latino districts besides SD26 in this list. We’ve discussed SD06 before, which had a big uptick in Democrats while seeing fewer Republicans in 2016, then saw more Republicans turn out in 2020. In the end, the Dem percentage was basically the same in 2020 as in 2012, with a larger net margin, but the trend needs watching. SD19, which Dems took back in 2020 after that embarrassing special election loss, had a similar pattern as with SD06 except with a smaller net Republican gain in 2020. This district has a lot of border turf, which trended red in 2020, but it also has a good chunk of Bexar County, which got bluer and likely mitigated the overall shift. I feel like this district is more likely to drift in a Republican direction than SD06 is, but that will depend to some extent on how it’s redrawn. SD29, anchored in El Paso, had the same big Dem shift in 2016, then saw roughly equivalent gains by both parties in 2020. I think it’s more likely to get bluer over time, and there’s always room for Dem growth in El Paso, though as with SDs 13 and 23, it will require engagement.

Overall, these 19 districts represent a net gain of over 900K votes for Dems. Joe Biden collected about 600K more votes than 2012 Obama did, so there’s votes going the other way as well. Here are those districts:

Here’s the current Senate map, to remind you of where these districts are. SDs 22 and 24 have the most turf inside the big population triangle, while SD04 has most of its people there. SD22 currently includes Johnson and Ellis Counties, and it’s not too hard to imagine them beginning to trend blue over the next decade, while SD24 includes Bell and Coryell, which also have that potential.

I’m actually a little surprised to see that SDs 04 and 18 got a little bluer in 2016, before snapping back in 2020. I’ll have to take a closer look at them, on a county by county basis, to see what the big factors were. Fort Bend is going our way, and I have hope that we can make progress in Montgomery, and that’s going to be a big key to this decade.

The big Republican gainers, as noted in the last post, are mostly in East Texas and West Texas/the Panhandle, with SD03 including the north part of Montgomery. The main question will be how much of these districts will have to include the faster-growing parts of the state. That’s a calculation that won’t be very friendly to the incumbents, one way or another.

Finally, there are the three Latino districts, SDs 20, 21, and 27. All three followed the same pattern of a Dem gain in 2016 followed by a bigger Republican gain in 2020. SD27 remained solidly Democratic, while 20 and 21 are much closer to swing status though as noted in the previous post the incumbents all ran comfortably ahead of the pack. Republicans could certainly try to make a district more amenable to them out of this part of the state. How that would affect their other priorities, and how much of what we saw in 2020 continues past that year are the big questions. All other Dems carried these three districts as well, more or less at the same level as Biden. The good news for the Republicans then is that the new voters that Trump brought in were there for more than just him.

As you can see, there are fewer districts in which Dems lost ground, and the total number of votes they ceded is about a third of what they picked up elsewhere. You can see how G. Elliott Morris’ tweet thread applies here. As was the case with the State House and Congress, the Republican gerrymander of the State Senate in 2011 was very effective, until it wasn’t. It’s the same story here as it is for the other chambers, which is how do they assess the risk of a strategy that aims to gain them seats versus one that just aims to hold on to what they’ve got.

Next up will be a look at the State House district results from 2020. When the 2020 data for Congress and the SBOE finally show up, I’ll do the same for them as well. Let me know what you think.
