About this Poll
This survey was conducted using an online sample supplied by Survey Sampling International (n=400) and via an automated telephone platform (IVR) using registered voter landline phone lists supplied by Aristotle, Inc. (n=400) for a total sample size of n=800 registered voters with a margin of error of +/- 3.4 percentage points. It is important to point out that subsets have higher margins of error, as the sample size is reduced. The margin of error for the Democratic Primary (n=271) is +/- 5.9 percentage points and for the Republican Primary (n=262) is +/- 6.0 percentage points. The data was collected July 20-July 21, 2018 and weighted by ethnicity, region, party affiliation and gender.
