About this Poll
The sample size for the survey is 500 likely general election voters in North Carolina and the margin of error is +/-4.38% at a 95% confidence interval, meaning that if this survey were repeated, results would not vary from the population by more than 4.38 percentage points 19 times out of 20. Responses were gathered via landline and mobile telephone interviews conducted by live callers at a professional call center. Demographics were adjusted to reflect the population from which the sample was drawn. The survey was conducted May 26 – 28, 2020 by Harper Polling. The total percentages of responses may not equal 100% due to rounding.
