Which Candidate Does Early Voting in Texas Favor?

One of the key questions about tonight's vote is what the composition of the electorate will be like in Texas (See Mark Blumenthal's excellent post on this topic). If African American turnout is up, then that will certainly favor Barack Obama, who does very well with that constituency. On the other hand, if Hispanic turnout is high, then Hillary Clinton should benefit.

One way to get a sense of what turnout may look like is to look at what the early voting figures look like. The Texas Secretary of State made available data on how many people voted early in Texas's 15 most populated counties. While this is merely a snapshot of the state as a whole, it is still worth looking at. Therefore, I have appended turnout data from the 2004 Democratic presidential primary in Texas and census data on the percentage of each county's population that is black, Hispanic, and white. These figures are below (the early voting numbers are just those voting in the Democratic Primary...Republican primary voters are not included):


The key column here is the fourth one, which presents the early voting in 2008 as a percentage of turnout in 2004. The first striking thing here is the great increase in turnout in 2008. In Denton County, six times as many people have voted early in 2008 as voted at all in 2004. Most people estimate that early voters will comprise one-third of the electorate in 2008, just to give a sense of how much turnout will be up throughout the state in 2008.

More importantly for understanding what the electorate might look like is comparing the percentage increase in turnout with the racial and ethnic data. Interestingly, it looks like early voting is greatest in the counties that have the highest percentage of non-Hispanic whites. Whites have split relatively evenly in primaries up to this point, so this may not strongly advantage either candidate.

Fort Bend County sticks out in this analysis because it is the county (among these 15 most populated counties) with the highest percentage of African Americans. Early voting in Fort Bend is over 3 times greater than overall turnout in 2004, and given Obama's edge among African Americans, this should benefit him.

Interestingly, the counties with the largest Hispanic populations have seen the lowest amount of early voting.

Of course some types of voters may be more likely to vote on election day rather than cast their ballots early, so it is important not to draw too much from this data. But, based on early voting, we may see turnout increase more among African American voters than it does among Hispanics. If that is the case, then it should benefit Obama. Of course, we will soon know not just what the electorate looks like, but which candidate that electorate favored.

The counties with the biggest jump in early voting are generally upscale and higher education counties surrounding Dallas and Austin, Obama demograpics. I don't have any evidence but a theory on this topic. Many of these voters may have voted early so they could attend the caucuses without a strain on their schedule. This would suggest a strong Obama performance in the caucuses in these areas.

Based on your chart, Harris, Dallas and Bexar counties have the largest voter base - 0.9-1.8 million voters, and their Hispanic populations are from 38%-57%. So even though the % increase in early voters may not be as large as in other counties, the absolute number increase is much greater in these almost-Hispanic-dominated communities.

Of course, whether the increase is due to Hispanics or other folks - we don't know, do we?
Also, what are the chances that an early-voter would also participate in the evening caucus, compared to someone who votes late today?

So many intriguing possibilities... :-)

Having worked the polls in Texas for going on 32 years, I can tell you that early voters tend to be older party loyals who select a day/time that reduces the chance of their having to tolerate long lines and/or waiting times to vote, or risk bad weather. Unfortunately many of these elderly voters are also less likely to attend the caucus because they are held late in the evening. Moreover, many who vote early are like myself. Because they are working the election, they vote early and then go straight to the caucus afterward. I disagree with the idea that most are higher income or well educated. In fact it is quite comically noted that this group tends to wait till the last minute and barely get in the doors before they close.
