The online poll shows Clinton with 50.22 percent, to Trump's 45.53 percent and 4.25 percent choosing "other." In the poll, "others" are defined as respondents who decline to pick Clinton or Trump.
The poll showed Clinton lost almost 1 percentage point percent in comparison with the day earlier, while Trump gained the same amount over the same time period. The day before Clinton led by 6.59 percentage points and her 51.17 percent support was the highest in polling since the beginning of July.
One week ago, Clinton led by 5.53 percentage points. But through Oct. 5, Trump had a lead for eight consecutive days.
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 Oct. 10 to 16, when 1,861 individuals were surveyed. Of them, 1,325 identified themselves as likely voters.
