The online poll shows Clinton with 49.69 percent to Trump's 45.47.
The most recent data reflect a 1.19 percentage point shift toward Trump and a loss of 1.15 percentage points by Clinton. A day earlier Clinton held a more-than 6-point lead. Over the course of a full, seven-day sample of the poll, both candidates have largely held steady, with Clinton gaining 0.2 percentage points and Trump gaining 0.3 percentage points over the past week.
The UPI/CVoter online tracking poll surveys about 200 people each day, leading to a sample size of roughly 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 Aug. 11-17, when 1,397 individuals were surveyed. Of them, 1,009 identified themselves as likely voters.
