Because the poll is conducted online and individuals self-select to participate, a margin of error cannot be calculated. The poll has a credibility interval of 3 percentage points. This seven-day span includes data collected from Aug. 23-29 when 1,695 registered voters were surveyed. Of them, 1,173 identified themselves as likely voters.
