Note on Methodology: The Loras College Poll surveyed 1,000 likely 2016 Wisconsin primary voters (including 416 likely Republican voters and 416 likely Democratic voters). The survey was conducted March 28-29, 2016. Margin of error for full sample results is +/- 3.1 percent, while for the party subsamples the margin of error is +/- 4.8 %. All results calculated at a 95 percent confidence interval.
Sample drawn from random selection of phone numbers of registered voters purchased through third-party vendor. For ballot questions related specifically to the April 5 election, only likely voters included. Screen for likely primary participation is report of “definitely,” “very,” or “somewhat likely” to vote on April 5 (and includes those who report to have already voted).
The total sample was balanced for gender and age, and divided across Wisconsin’s Congressional districts with reference to current registration. Sample includes both landlines and cell phones, with weighting applied to achieve 56 percent landline v. 44 percent cell in order to better approximate cell phone prevalence in population (unweighted cell phone split in sample was 72 percent landline to 28 percent cell).
The survey was conducted using live operator interviews through a contracted professional call center.
Script development and methodology used for the survey received input from Republican campaign consultant Brian Dumas and Democratic campaign consultant Dave Heller.
Note: Percentages are of weighted sample—see methodological note above.
(May not add to 100% due to rounding)
The Loras College Poll is conducted several times each year. Loras College faculty and student researchers work as part of the survey research team to develop poll questions, analyze and interpret data, and assist with sharing the final results with local, regional and national media.
