The online poll shows Clinton with 50.84 percent support to Trump's 44.28 percent
The most recent data reflect a slight increase for both candidates from data collected a day earlier. Clinton gained 0.17 percent to Trump's 0.09 percent increase.
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 Aug. 9-16, when 1,473 individuals were surveyed. Of them, 1,069 identified themselves as likely voters.
