Center for Opinion Research
The Department of Political Science & History operates a full scale polling center, which includes professional computer assisted telephone interviewing (CATI) software and 20 work stations for students to learn about survey research by experiencing how the data is collected.
The February survey by the Dallas Morning News and UT Tyler is the second poll that studied the views of Texas voters during the 2020 Primary Election. This survey is released the weekend before Super Tuesday when voters will cast their vote for each party's nominee for numerous offices. Our samples include 586 voters who indicated they would vote in the Democratic primary or leaned to the Democratic party (+/- 4.05%). The survey also includes 567 self-identified Republicans and Independents that lean to the Republican party (+/- 4.12%) who answered questions about the presidential and senate elections.
The online and phone surveys were conducted in English and Spanish. The poll was conducted during the ten days between February 17 and February 26.
The UT Tyler-Texas Opinion Survey reflects a statewide random sample of 1221 registered voters during the ten days between February 17 and February 26. The mixed mode sample includes 446 registered voters who took the survey by phone and 775 likely voters that were randomly selected from a panel of registered voters that have opted-in to take surveys through a company called Dynata. The online and phone surveys were conducted in English and Spanish.
The data were weighted to be representative of the Texas register voter population. Iterative weighting was used to balance sample demographics to the state population parameters. The sample is balanced to match parameters for gender, age, race/ethnicity, and education using an iterated process known as raking. These parameters were derived from 2018 Current Population Survey to reflect Texas’s electorate. The use of these weights in statistical analysis ensures that the characteristics of the sample closely reflect the characteristics of registered voters in Texas.
In this poll, the sampling error for 1221 registered voters in Texas is +/- 2.8 percentage points at a 95 percent confidence interval. The survey’s design asked additional questions to 586 likely voters who indicated they would vote in the Democratic Primary (margin of error of +/- 4.05%). Similarly, there were 567 likely voters to represent the electorate in the Republican primary (margin of error of +/- 4.12%).
