UPI/CVoter poll: Clinton, Trump nearly tied a week before election

WASHINGTON Nov. 1 (UPI) -- The UPI/CVoter daily presidential tracking poll for Tuesday shows Hillary Clinton leading Donald Trump by just over 1 percentage point.

The online poll shows Clinton with 48.81 percent to Trump's 47.71 percent with one week to go before the election.

Clinton gained nearly a half point and Trump declined slightly compared to data collected a day earlier though over the course of a week, the poll's full sample size shows Trump gaining ground to the tune of 1.32 points, with Clinton declining 0.65 percent, leaving the race in nearly a dead heat.

A race this close will likely hinge on turnout, especially along gender lines in battleground states. A state-by-state analysis of the UPI/CVoter tracking poll shows Clinton leading in the Electoral College.

The UPI/CVoter online tracking poll surveys more than 200 people each day, leading to a sample size of at least 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 Oct. 24 to 30, when 1,874 individuals were surveyed. Of them, 1,299 identified themselves as likely voters.
