UPI/CVoter poll: Donald Trump widens lead over Hillary Clinton to 2 points

WASHINGTON Sept. 11 (UPI) -- The UPI/CVoter daily presidential tracking poll released Sunday shows Donald Trump leading Hillary Clinton by 2 percentage points.

The online poll shows Trump with 48.23 percent to Clinton's 46.06 percent.

The most recent data reflect a 1.09 percentage point shift toward Trump compared to data collected a day earlier and a shift of more than 5 percentage points toward Trump in the spread between the two candidates over the course of seven days, the poll's full sample size.

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. 2 to 8, when 1,837 individuals were surveyed. Of them, 1,256 identified themselves as likely voters.
