Both candidates lost ground slightly compared to data collected a day earlier and the race has remained almost exactly steady over the course of the past seven days, the poll's full sample size.
The UPI/CVoter online tracking poll surveys more than 200 people each day, leading to a sample size of at least 1,400 people during any seven-day span.
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 Sept. 8 to 14, when 1,851 individuals were surveyed. Of them, 1,265 identified themselves as likely voters.
