WASHINGTON, Sept. 14 (UPI) -- The UPI/CVoter daily presidential tracking poll for Wednesday shows Donald Trump leading Hillary Clinton by 3 percentage points.

The online poll shows Trump with 48.9 percent, to Clinton's 45.72 percent.


The most recent data is virtually unchanged from the day before. Trump has held a lead in the UPI/CVoter tracking poll for the last week, the poll's full sample size.

The UPI/CVoter online tracking poll surveys at least 200 people each day, leading to a sample size of more than 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. 6 to 12, when 1,792 individuals were surveyed. Of them, 1,232 identified themselves as likely voters.
