*Updated November 4 to reflect most recent polling.
With the start of early voting and Election Day drawing near, it's worth looking at the trajectory of the publicly available (non-campaign) polls on the Texas Governor's race over the course of the Summer and Fall. Each of the tables below shows results for likely voters as defined by those individual surveys. A few important characteristics of the overall body of polling should make themselves apparent with a cursory inspection:
- Abbott has lead in every statewide poll by double digits in all but one (in which he lead by 9). The average lead for Abbott has been 13.87 points.
- Abbott has a substantial lead among Texas men, and Davis appears to be closing the gap with Texas women, which would represent an improvement on Bill White's performance in 2010.
- Hispanics are notoriously hard to reach in polling, regardless of method. This has played out in the variance of the results seen in Table 2, but there are two very important points to remember about Hispanic sub-sample estimates: one, they are subject to extremely high margins of error (roughly +/-8 percentage points depending on one's assumptions); and two, swings between differing estimates don't actually produce substantially different election outcomes because despite the rapid growth rate of the Hispanic population in Texas, they still make up a small proportion of the electorate – especially in a midterm election. You can compare the results from Table 2 to the results based on 2010 exit polling in Table 3. If you're considering the potential growth of the Hispanic share of the electorate, it grew from 15 percent to 17 percent between 2006 and 2010.
- Finally, the racial composition of the 2014 electorate, and the relative vote propensities of Hispanics in particular, is an open question, and one that we'll all be interested in learning more about after Election Day upon the release of exit polling information. But good public polling doesn't begin with assumptions about what the electorate is going to look like or how a certain racial/ethnic group "should" vote. Table 4 and Table 5 show the demographic compositions from 2010, and then from the public polling since June 2014.
