The UPI/CVoter daily presidential tracking poll released Monday shows Donald Trump leading Hillary Clinton by about 3 percentage points.

The online poll shows Trump with 48.7 percent to Clinton’s 45.8 percent in the seven-day polling period ending Sunday. Those responding with “others” were at 5 percent. “Others” in the poll are defined as respondents who decline to pick either Clinton or Trump.

The most recent data reflect a 0.8 percentage point shift toward Clinton compared to data collected a day earlier. Trump was at nearly 50 percent — 49.1 percent — compared with 45.3 percent for Clinton in the seven-day polling period ending Saturday. Trump’s highest number since July 14 was 49.2 percent on July 24.

Seven days ago, Clinton had a 2-point lead with 48.1 percent compared with 46.1 for Trump in the spread between the two candidates over the course of seven days, the poll’s full sample size. Clinton’s high was 50.8 on Aug. 16.

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 Sept. 5 to 11, when 1,815 individuals were surveyed. Of them, 1,260 identified themselves as likely voters.
