The University of New Orleans Survey Research Center conducted an interactive voice response (IVR) telephone survey on January 11, 2018 on the topic of candidate choice in a hypothetical match-up between President Donald Trump and Oprah Winfrey. Survey respondents were randomly selected from the Louisiana Secretary of State’s registered voter file. The sample of 722 respondents yields a margin of error of 3.7% with 95% confidence.
