The UPI/CVoter daily presidential tracking poll for Friday shows Hillary Clinton and Donald Trump in a virtual tie four days before the election.

The online poll shows Clinton with 48.53 percent to Trump's 48.44 percent, a 0.1 percent difference.


The most recent data reflect virtually no change from a day ago and a shift of just 1 percentage point upward for Trump over the past seven days, the full sample size for the poll.

The UPI/CVoter online tracking poll surveys at least 200 people each day, leading to a sample size of roughly 1,400 people during any seven-day span.

The effect of the FBI's revelation it came across new emails relevant to the Clinton email investigation is now fully included in the survey. Over the course of those seven days, Trump continued to rise in the polls, though Clinton maintains an advantage in key battleground states.

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 Oct. 28 to Nov. 3 when 1,973 individuals were surveyed. Of them, 1,395 identified themselves as likely voters.
