Precinct analysis: Undervoting in judicial races

Last time, we looked at undervoting by State Rep district in the two city propositions, which were at the very end of the 2018 ballot. That showed a somewhat greater likelihood of people in Democratic districts to skip those races, which was the first real evidence to support the assertion that Dems might suffer more in the post-straight ticket world. I said this was suggestive but far from conclusive, since we were looking at non-partisan referenda, with no candidates involved.

So with that in mind, let’s look at undervoting in a few of the judicial races that were on the ballot this year. These are also low profile and deep into the ballot, but they do provide the cue of party identification. What if any patterns do we see in the tendency to not vote in these races? To try to answer this, I looked at six judicial races, three of the first ones that appear and which have an overall low undervote rate, and three that appear near the end and which have an overall high undervote rate.

As before the undervote rate is calculated by subtracting out the straight ticket votes from the total turnout in each district, so the percentage is (undervotes) / (non-straight ticket votes). There are three things to note here.

1. Three strong Democratic districts, HDs 131, 141, and 142, are consistently among those with the lowest undervote rates. Two strong Republican districts, HDs 129 and 133, are consistently among those with the highest undervote rates. There are also Democratic districts (HDs 140, 143, 145, 148) with high undervote rates, and Republican districts (HDs 126, 127, 128, 130, 150) with low undervote rates. The message is mixed.

2. If we zoom in on the most even districts – HDs 132, 134, 135, and 138 – we see that as we move from the races with overall low undervote rates to the races with the overall high undervote rates, the Democratic percentages in these districts increased in two of the three races. This is also the case for Democratic majority districts – look at HDs 144, 145, 146, and 147, for example. In other words, the voters that are dropping off are for the most part not those that are voting for Democratic judicial candidates.

3. Pulling back out to the bigger picture, the total number of votes affected here is really small. Look at HD148, one of the highest-undervote districts. The total number of undervotes there ranges from 2,189 to 2,545, a difference of 356 votes. As I said weeks ago, the range of undervotes in these judicial races is something like 31K to 36K, so maybe about five thousand more people drop off at the bottom of the ballot than in the middle, where we start voting for judicial candidates. That’s not a lot of votes! The Democratic judicial candidates in 2018 all won by at least 100K votes. The closest judicial race in 2016 was decided by 23K votes. You’d need to have a really big dropoff rate and a really big partisan differential for there to be a chance this could have an effect. There is zero evidence for either of these.

Now look, I admit that I am not a Professional Political Scientist. If I were, I’d probably being doing linear regressions or other fancy mathematical analyses to try to rigorously tease out possible correlations. I’m just a lowlife blogger fooling around in Excel while I watch the Texans game. But again, that’s my whole point about these ridiculous claims about “voter fatigue” and “Republican voters are more committed”, which is SHOW ME THE FRICKING EVIDENCE FOR THESE CLAIMS. I’m doing my amateur-level best to try and find it, and I can’t. If anything, I’m finding evidence for the opposite. Prove me wrong! I double dog dare you!

Anyway. I still have one last post on this topic, then I will go back to looking at precinct data in the way you’re more used to me looking at it. I hope you have found this useful.

2 Responses to Precinct analysis: Undervoting in judicial races

  1. Ronald Wilson says:

    Each party has time to educate voters about finishing the ballot. As far as 2018 midterm election, change came in the urban counties especially in the suburbs.

  2. Houston is so…

    desperate for leadership they are still begging me to run in at-large 5.

    I could run in district h because we know karla cisneros has no bipartisan ideas for the low-income community she serves.

    Her time on the houston isd board was a joke.
