The online poll shows Clinton with 48.81 percent to Trump's 48.14 percent with six days to go before the election. Those responding as "other" -- declining to pick either candidate -- were at 3.05 percent.
Clinton improved her lead slightly and Trump dropped a little from the previous day -- 48.3 for Clinton and 48.28 for Trump. "Other" was at 3.42.
Clinton's lead was slightly higher -- 1.38 percentage points -- before FBI Director James Comey announced Friday a review of additional emails in connection with Clinton's use of a private email server while she was secretary of state.
A state-by-state analysis of the UPI/CVoter tracking poll released earlier this week shows Clinton leading in the Electoral College.
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. 26 to Nov. 1, when 1,975 individuals were surveyed. Of them, 1,383 identified themselves as likely voters.
