WASHINGTON, Oct. 19 (UPI) -- The UPI/CVoter daily presidential tracking poll released Wednesday shows Hillary Clinton leading Donald Trump by 4.88 points as the presidential candidates head into their final debate.

The online poll shows Clinton with 50.53 percent, to Trump's 45.63 percent and 3.82 percent choosing "other." In the poll, "others" are defined as respondents who decline to pick Clinton or Trump.


Clinton's lead changed slightly from the last poll when the Democrat was ahead by 4.69 percentage points in polling one day earlier. She gained 0.33 and her Republican challenger went up 0.12.

Clinton has led in polling for 11 consecutive days. During this stretch the latest poll is the first time "others" was below 4 percentage points.

The Democrat's biggest lead was 6.59 percentage points and her 51.17 percent support was the highest Saturday in polling since the beginning of July.

One week ago, Clinton led by 6.14 percentage points. But through Oct. 5, Trump had a lead for eight consecutive days. The Republican's biggest advantage was 4.85 percentage points through July 23 -- two days after the Republican National Convention.

Clinton's lead continues in the fallout of a video that showed Trump joking about groping women and the most recent debate, where Trump dismissed his comments as "locker room talk." Also since the second debate Oct. 8, several woman have said they were sexually assaulted by Trump.

Clinton and Trump face one another for the final time Wednesday night in a 90-minute debate.

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 Oct. 11 to 17, when 1,876 individuals were surveyed. Of them, 1,326 identified themselves as likely voters.
