Methodology
The Emerson College Polling Louisiana survey was conducted April 24-26, 2026. The overall sample of Republican likely primary voters, n=500, has a credibility interval, similar to a poll’s margin of error (MOE), of +/- 4.3 percent. The data sets were weighted by gender, education, race, age, party registration, and region based on U.S. Census parameters and voter file data.
It is important to remember that subsets based on demographics, such as gender, age, education, and race/ethnicity, carry with them higher credibility intervals, as the sample size is reduced. Survey results should be understood within the poll’s range of scores, and with a confidence interval of 95% a poll will fall outside the range of scores 1 in 20 times.
Data was collected by contacting an online panel of voters provided by Consensus Strategies using MMS text-to-web. Panel responses were matched to the Aristotle voter file using respondents’ full name and ZIP code. The survey was offered in English. All questions asked in this survey with exact wording and order, along with full results, demographics, and cross tabulations can be found below.
