Unless otherwise stated in individual crosstabulation reports, the sampling error for the national primary electorate is ± 2.1% at a 95% confidence interval.
All BIG DATA POLL publicly conducted surveys are crowdfunded via the Public Polling Project, supplemented if necessary by BIG DATA POLL and are NOT funded by or affiliated with any candidate, campaign, committee, or political entity.
