A poll of 1,409 likely Texas voters found that 82 percent support requiring proof of U.S. citizenship when registering to vote, according to Heritage Action, which commissioned the survey. The poll was conducted October 10–15 through live calls, online panels and automated telephone interviews. It has a reported margin of sampling error of plus or minus 2.61 percentage points. By party, 94 percent of Republicans, 83 percent of Independents and 66 percent of Democrats supported the requirement.

The poll also found majority support across parties for requiring agencies to correct voter records, showing citizenship status on state-issued identification, and requiring the secretary of state to report each year how many voter registrations were removed due to ineligibility. Allowing provisional ballots for people whose citizenship could not be verified was the only election question without majority support from both parties. More than 65 percent of Republicans surveyed opposed it, while 56 percent of Democrats supported it.

In the U.S. Senate race, more than 80 percent of Republicans said they would vote for Ken Paxton and 10 percent for James Talarico, with 9 percent undecided. Among Democrats, 90 percent said they would vote for Talarico and 3 percent for Paxton. Stefani Buhajla, Heritage Action's senior communications director, said, "Election integrity and voter access do not have to be competing goals."
