SURVEY METHODOLOGY

The overall margin of sampling error for the 712 completed interviews with Hispanic respondents is +/- 5.2 percentage points, and for the 528 completed interview with Black respondents, the margin of sampling error is +/- 5.7 percentage points. [...] In total, 82 interviews were removed for nonresponse to at least 50% of the questions asked of them, for completing the survey in less than one-third the median interview time for the full sample, or for straight-lining all grid questions asked of them. [...] The sample is also weighted to match the average of self-identified party identification in the previous two waves of the AmeriSpeak Omnibus survey and this current survey.
